This article examines the types and cooking methods of Suksilkwa as recorded in 14 royal palace studies and 10 old literature texts of the Joseon dynasty (1392-1909). The types of Suksilkwa during the Joseon dynasty were Joran (棗卵), Yulran (栗卵), and Gangran (薑卵). The frequency of the Suksilkwa types during the Joseon dynasty in order were: Gangran (35.4%), Joran (32.3%), and Yulran (32.3%). Prior to 185 years ago, "Junghae-Jungraeeuigwe (丁亥整禮儀軌)" (1827), Joran (棗卵), Yulran (栗卵), and Gangran (薑卵) were called Samsaegran (三色卵). Nearly 144 years ago, "Mujin-Jinchaneuigwe (戊辰進饌儀軌)" (1868) recalled sulsilgwa (熟實果). "Imjin-Jinchaneuigwe (壬辰進饌儀軌)" (1892) first recalled assorted-sulsilgwa (各色熟實果), in which sansabyeong were added in the sulsilgwa. "Sinchuk-Jinyeoneuigwe (辛丑進宴儀軌)" (July 1901), "Imin-Jinchaneuigwe (壬寅進饌儀軌)" (April 1902), "Imin-Jinyeoneuigwe (壬寅進宴儀軌)" (November 1902) described assorted-sulsilgwa (各色熟實果) in which ohmijabyeong were added to the sulsilgwa. Further study will be conducted on recipes and ingredients recorded in these Euigwe and old books in order to develop a standardized recipe to make Suksilkwa appealing to a global palate.

This study examined the prevalence of the traditional fruit preserve, gwapyeon, recorded in 10 royal palace studies and 10 old literature reports on the Joseon dynasty (1392-1909). A total of 62 papers presented the Gwapyeon kind in the documents of the Joseon dynasty. The protocols of the court of the Joseon Dynasty and old literature discussed the Gwapyeon as follows: Nokmalbyeong (ohmijapyeon) 22.5%; aengdupyeon (櫻桃片) 14.5%; salgupyeon (杏) and bokbunjapyeon (覆盆子) at 11.3% each; beojjipyeon and mogwapyeon (木瓜) at 8.1% each; sansapyeon (山査) and chijapyeon at 6.5% each; duchungpyeon (杜沖) 4.8%; and deuljjukpyeon, saenggangpyeon (薑), daechupyeon (棗) and yujapyeon (柚子) at 1.6% each. From "Junghae-Jungraeeuigwe (丁亥整禮儀軌)" (1827) to "Junghae-Jinchaneuigwe (丁亥進饌儀軌)" (1887) called nokmalbyeong (菉末餠). "Sinchuk-Jinchaneuigwe (辛丑進饌儀軌)" (May 1901) renamed the ohmijabyeong (五味子餠). "Sinchuk-Jinyeoneuigwe (辛丑進宴儀軌)" (July 1901), the assorted-sulsilgwa (各色熟實果 ) were included in the ohmijabyeong. "Imin-Jinchaneuigwe (壬寅進饌儀軌)" (April 1902), The ohmijabyeong (五味子餠) and assorted-sulsilgwa (各色熟實果) was used and a mixture of "Imin-Jinyeoneuigwe (壬寅進宴儀軌)" (November 1902) included the assorted-sulsilgwa (各色熟實果).

안평대군이 주도하고 군신들과 안견이 참여하여 제작된 ≪비해당소상팔경시첩≫은 <몽유도원도>와 함께 조선 초기에 높은 수준을 이룩한 시화 제작의 전형이었을 것으로 생각된다. 1442년에제작된이 시첩에는당대 문사들의 소상팔경시와 함께 소상팔경도가 그려져 있었으나 현재 그림은 산실되고 시문만 첩의 형태로 전한다. 여러 가지 정황으로 보아 ≪비해당소상팔경시첩≫에 소상팔경도를 그린 화가는 안견으로추정된다. 안견은 조선초기에활약한 최고의 산수화가로 그가 이룩한 화풍은 당대는 물론 후대의 산수화에 지대한 영향을 미쳤다. 현존하는 조선초기의 소상팔경도중 상당수가 안견의 전칭을 지닌 점도 시사하는 바가 크다. ≪비해당소상팔경시첩≫제작의계기가된 남송寧宗의 팔경시 는 여러가지로 중요한 의미를 지니고있다. 남송영종의 팔경시 는팔경의순서에 새로운 변화를 보여주며, 조선초기에 제작된 소상팔경도의 순서에 많은 영향을준 것으로 생각된다.안견이 그렸을것으로 추정되는≪비해당소상팔경시첩≫의<소상팔경도>역시 영종의 팔경시 의 순서를 따랐을 가능성이 높으며, 이그림 이후대의 소상팔경도에 많은 영항을 주었을 것으로 추정된다. 조선초기의 소상팔경도중≪비해당소상팔경시첩≫과 가장 연관이 깊은 작품은 구幽玄齋 소장의<소상팔경도>로 생각된다. 그림의 순서와 화제의 표기 방식등이 유일하게 남송영종의 팔경시와 일치한다. 팔경이 개별적으로 독립된 작품이면서 하나로 이어지는 유기적인 구성을 보이는 점 에서도≪비해당소상팔경시첩≫의 시의내용과도 부합한다. <소상팔경도>에 그려진 각 폭의내용도남송영종의 팔경시 를 비교적 충실하게 따라 그린듯이 크게 어긋남이 없다. 유현재본 <소상팔경도>는 북송대에서 명대에 이르는 李郭派 화풍의작품들과 많은 공통점이 있다. 아울러 소재와 표현에서 안견의 <몽유도원도>와도 유사성이 인정된다. 유현재본 <소상팔경도>는 안견이 그린 것으로 추정되는 ≪비해당소상팔경시첩≫의 소상팔경도를 충실히 임모하거나 방한 작품으로 생각된다. 조선 초기와 중기의 다른 소상팔경도 및 산수도 중에서 많은 작품이 유현재본 <소상팔경도>와 많은 연관을 보이는 것도 ≪비해당소상팔경시첩≫의 안견의 <소상팔경도>가 범본範本으로서 후대 작품에 미친 지대한 영향으로 추정된다. 앞으로≪비해당소상팔경시첩≫과 유현재본<소상팔경도>의 연관이 보다 분명하게 밝혀진다면 산실된 안견의<소상팔경도>에대한 단서를 얻을 수 있으며, 안견의<소상팔경도>가 후대작품에 미친 영향 및 조선초기 소상팔경도의 전개과정에 대해 보다 구체적인 분석과 이해가 이루어질 것으로 기대된다.

The purpose of this study lies on reinterpreting the geography books in Joseon dynasty as records of the cities and consequently suggesting directions for further urban research. Geography books of Joseon dynasty are valuable references to understand the national policy, and imply that the focus of the contents is on the system. Especially, military system is an important concept to understand city type in that period, relationships between cities, selection of location, etc. The results of review are as following: First, military system is not a permanent fixture and therefore reflects changes in urban policies along with the history. The system suggests valuable clues on urban development as it is state-run, and closely associated with national land development. Second, counties and prefectures under jurisdiction of district called Eupchi(邑治) had cities as important as or even more important than local government such as Yeong-a(營衙), Jinbo(鎭堡), Yeok(驛: administrative cities). Such special regions need to be studied as other type of cities in Joseon dynasty by defining their architectural characteristics and roles. Third, the relationship of cities such as Eupch, Yeong-a, and Jinbo, was reorganized according to the local military system. Eupchi, administrative city, along with Yeong-a and Jinbo evolved into a military city as it became systematically organized. The characteristics of Yeok needs to be reconsidered in the context of such new inter-city relationship. Fourth, considerations which should be reviewed in the geography based on this concept can be mainly classified into architecture and landscape. This will also lay the foundation, and suggest new directions for further research for Eupchi, Yeong-a, Jinbo, and Yeok. Fifth, description of the geography looks simple at first sight, but with thorough understating on the system, there are chances to interpret objective reasoning of position and landscape in the overall flow of region, area, etc. Bongsu(烽燧), signal-fire, can be an object of comparison with geographical features and position. Furthermore, advantageous position is a historical and geographical element showing the major context of the region.

On behalf of the royal women, SangGung(尙宮:The head of female servants in the palace) and NaIns(內人: Female servants caring for royal families in the palace) were dispatched in order to attend a funeral at the royal tomb. The NaInGaGa(內人假家) is the temporary building for SangGung and NaIns in the royal tomb. It is comprised of lodgings for them and also workrooms and warehouses to prepare ritual offering for the dead King or Queen. In the early Joseon dynasty, the NaInGaGa was utilized until a funeral at the royal tomb. Since 1674, NaInGaGa for the 3 years-period lamentation was started constructing separately. At these processes, the plan and placement of NaInGaGa was changed. This study based on the SanReungDoGam-EuiGwae (山陵都監-儀軌: The report on constructing royal tomb). The SanReungDoGam-EuiGwae written since 1800 have illustration about NaInGaGa. The illustration and explanation about NaInGaGa become a important clue that make suppose detailed space of NaInGaGa

Astronomical data making such as forming a calendar, period of day, determining the time of rising/setting of the sun and the onset of twilight are essential in our daily lives. Knowing the calendar day of the past is particularly crucial for studying the history of a clan or a nation. To verify previous studies in the calendar day of the Joseon dynasty (1392 – 1910), we investigate the sexagenary cycle of the new moon day (i.e., the first day in a lunar month) by using sources such as results of the calculations using the Datong calendar (a Chinese Calendar of the Ming Dynasty) and the data of Baekjungryeok (a Perpetual Calendar; literally, a one hundred-year almanac). Compared with the study of Ahn et al., we find that as many as 17 sexagenary cycles show discrepancies. In the cases of nine discrepancies, we find that the sexagenary cycles of this study are identical to those of the almanacs at that time. In addition, we study five sexagenary cycles by using the historical accounts of Joseon Wangjo Sillok (Annals of the Joseon Dynasty), Seungjeongwon Ilgi (Daily Reports of Royal Secretariat), Chungung Ilgi (Logs of Crown Prince), and so forth. For the remaining discrepancies, we present historical literature supporting the results of this study. This study will greatly contribute to the identification of the lunisolar calendar days during the Joseon dynasty as the dates of the modern (i.e., Gregorian) calendar.

This article examines the types and cooking methods of Soondae (Korean Traditional Sausage) as recorded in 12 books of the Joseon dynasty (1392-1909). The ingredients used in Soondae during the Joseon dynasty were dog meat, beef, pork, lamb, and fish. There were no recorded mentions of Soondae in the early Joseon dynasty, but by the middle period there were three different dishes recorded. By the late era of the Joseon dynasty that number had increased to twelve. During the middle era of the Joseon dynasty, one kind of Soondae was prepared using dog meat, one using beef, and one using pork. By the late Joseon dynasty, there were six types of Soondae prepared using beef. They also had three kinds of Soondae prepared using lamb and two using fish, one using pork by that time. The frequency of the Soondae ingredients during the Joseon dynasty in order were beef (46.7%), lamb (20%), pork (13.3%), fish (13.3%), and dog meat (6.7%). Further study will be conducted on recipes and ingredients recorded in these old books to develop a standardized recipe in order to make Soondae appealing to a global palate.

The Ganui (簡儀, simplified armillary sphere) is a representative of astronomical instruments in Joseon Dynasty of Korea, as well as Yuan Dynasty and Ming Dynasty of China. In early 15th century, Joseon's scientists and engineers uniquely developed the Soganui (小簡儀, small simplified armillary sphere) and the Ilseongjeongsiui (日星定時儀, sun-and-star time determining instrument) from the structural characteristic of Ganui. These two astronomical instruments had a new design by the miniaturization and felt convinced a similar performance of Ganui in the harmony with Korean Astronomy and Astrology Cultures. Since mid-18th century after the enforcement of shixian-li (時憲曆), the Soganui and Ilseongjeongsiui handed over the Jeokdogyeongwiui (赤道經緯儀, equatorial armilla) by a change of the observational framework such as the time and angle measures. The Jeokdogyeongwiui made by Gwansanggam (觀象監, Bureau of Astronomy in Joseon Dynasty) adopted the new observational framework. We studied the structural characteristics and scientific values of these 3 astronomical instruments with theirs observation methods.

This study examined the prevalence of the traditional pressed sweet called dasik recorded in 15 Joseon dynasty (1392-1909) royal palace studies. The ingredients used in Dasik during the Joseon dynasty were categorized into 43% cereal powders, 18.6% tree fruits, 17.4% flower powders, 11.6% root clods, 8.2% dry-fish beef powders, and 1.2% vegetables. In the early era of the Joseon dynasty there were no reports of dasik in the royal palace. In the middle era of the Joseon dynasty there was one report of dasik in the royal palace. But in the late era of the Joseon dynasty there were 85 kinds of dasik reported in the royal palace. The most common ingredients were, most common first, Song-wha (松花), Huek-im (黑荏), Hwang-yul (黃栗), Nok-mal (菉末), and chungtae (靑太). The appearance and taste of dasik varied greatly throughout the time period, eventually resulting in nutrient supplementation. This observation may be associated with the commercial industrial development that prevailed during the late Joseon dynasty. Further investigation will be conducted on the recipes and ingredients recorded in these old studies to develop a standardized recipe for the globalization of dasik.

In this paper, we study the structure of the Daegyupyo (大圭表, Large Gnomon) of the early Joseon dynasty. A Gyupyo (圭表, Gnomon that is Guibiao as pronounced in Chinese) is composed of a Pyo (表, Biao as pronounced in Chinese) making a shadow and a Gyu (圭, Gui as pronounced in Chinese) measuring its length. It is known that the Daegyupyo with the 40-feet height was constructed between the sixteenth to seventeenth year of the King Sejong reign (1444 - 1445) on the basis of the record of Yuanshi (元史, the History of the Yuan Dynasty). By analyzing historical documents such as Joseonwangjosillok (朝鮮王朝實錄, the Annals of the Joseon Dynasty), Yuanshi, and Jegaryeoksangjip (諸家曆象集, a work written by Sunji Lee), we found a possibility that the Ji (池, a pond) on the Gyu was located in the north side of the Pyo. This structure is different from that in previous studies, but is in a good agreement with that of the 40-feet Guibiao remaining in Dengfeng (登封) of China. Regarding to the Hoengyang (橫梁, cross-bar), we suggest that it was set up by double 5-feet supporting arms apart from the north tip of the Pyo in the radial direction. The 3:4:5 ratio in a rectangular triangle was used to place the Heongyang on the top of the Pyo at a distance of 4-feet (3-feet) in the vertical (horizontal) direction. We also discuss the structural problem when the Hoengyang is positioned apart from the top of the Pyo by supporting arms. In conclusion, we think that this study should be useful in restoring the Daegyupyo of the Joseon dynasty.

This paper reviews 14 studies of the Joseon Dynasty(1392～1909) to examine the traditional Korean foods in Korean festivals. A total of 12 studies mentioned Seollal, Daeboreum, Dongji, Nappyeng as festivals involving. Traditional foods 10, Yudu, 9, Sambok and Junggujeol, 8, Chuseok and Seotdalgeummeum, 7, Samjinnal, Chopail, and Dano, 5, Jungwon, and 4, Hansik. In terms of the types of traditional foods, 13 studies mentioned red bean gruel, 12, Yaksik, 11, Tteokguk, 10, sudan and dog meat, 8, the custom of cracking the outer shell of different types of nuts, 7, Guibagisul(an ear-quickening wine), rice cakes(azalea hwajeon, zelkova rice cake, bean and turnip rice cake), 6, a chrysanthemum cakes, 5, Songpyeon, charunbeung(wagon-wheel rice cake), chrysanthemum wine, and sparrow meat, 4, Gangjeong, red bean grue, wine and snack, Jeonyak, 3, rice cakes, the making of soy sauce, Nabyak, roasted hare meat, foods for guests during, New Year festivities and rice cakes. The most frequently recorded festival foods were rice cakes and wine in various forms. This paper's review of ancient documents from the Joseon Dynasty provides a better understanding of Korea's folk customs, particularly traditional foods. In addition, this paper's findings are expected to help sustain Korea's traditional customs and foods and facilitrate the spread of Korea's food culture worldwide.

The purpose of this study is to understand the architectural space of Donggung(東宮), the Prince's Palace, and Dongjo(東朝), the King's Mother and Queen's living space, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Donggung(東宮) and Dongjo(東 朝) in Gyeongbokgung(景福宮), one of the Royal Palace, the result of this study is as followings. Donggung which was living space for Prince consisted of Jaseondang(資善堂), Seunwhadang(承華堂) and Kyejodang(繼照堂) in the era of King Sejong Kyejodang was demolished and Seunwhadang was destroyed by fire in King Jungjong era and was not rebuilded. This buildings The buildings consisted of Jeondang, Whudang, main gate, hapmun(閤門) and corridor or fence Donggung and Dongjo was separated wall Dong consisted of many buildings for Queen dowager, Queen and many royal concubines The arrangement of Donggung and Dongjo was assumed like as the Fig2.

Nakseonjae in Changdeokgung Palace was established at The King Hunjong’s 13rd year (1847), the mid-19th century. It was constructed for own rests of King Hunjong and the residence of Kyungbin (king’s concubines), and is showing features of upper-class houses from several points such as rustic architectural types by getting out of authoritative aspects as king’s shelter space within the palace, block and floor distribution that separated spaces for men and women, simplicity in structures and styles, and non-colorful painting etc. This study aims at tracing on which architectural types did the upper-class houses within Hanyang (modern Seoul) at late Joseon Dynasty have and what was characteristics of Nakseonjae. The resemblance between Nakseonjae and the upper-class houses was very little differences from scale aspects, and floor plan shapes of Anchae (women’s quarters) and Sarangchae (men’s quarters) were followed basic common styles. Also, resemblance could be confirmed in the structural styles too. Characteristics of Nakseonjae are showing apparent differences from clearance compositions such as hall configuration etc. Nakseonjae was king’s dwelling place, and spaces for house’s collateral functions such as kitchen, stable, and warehouse etc together with shrine were unnecessary, and such places were substituted into servants’ quarters for assisting the Royal family. In detailed structural styles, column’s size was larger 3cm or more than the upper-class houses, and its height was higher to the degree of 30~60cm. Besides, formality as king’s shelter space was raised more in decorating aspects, and Nakseonjae was implemented by getting architectural influences from Qing Dynasty of China. This study induced features of Hanyang’s upper-class houses at the 19th century by supplementing distribution and space configurations at existing cases of Seoul and Gyeonggi area together with house diagrams having been collected by Gaokdohyung (site and floor plan) of Jangseogak Library, and confirmed resemblances and differences with Nakseonjae, that is, features of Nakseonjae. Through the result, this study judges a fact that architecture of Nakseonjae seemed to be affected from conveniences of upper-class houses within Hanseong, and also architectural styles and distribution types of Nakseonje would give influences to the upper-class houses.

The purpose of this study is to understand the architectural space of Chimjeon (寢殿), the King's Bedroom, and Backyard, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for King, living space for King and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of the King's Bedroom in the central area and Backyard in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. Cheonchujeon (千秋殿) and Manchunjeon (萬春殿) were not both sides of Sajeongjeon (思政殿), were on the north side of Gangnyeongjeon (康寧殿) Gangnyeongjeon was not a bedroom for the King and Queen, only for King. Bedroom for Queen was located another space in the Royal palace. There was Hamwonjeon on the west side of Koytaejeon. Jamidang and Cheongyeonroo were on the right side of Koytaejeon The Backyard on the north side of Gyeongbokgung had a wide area for horseback archery and the practice of battle formation The arrangement of the King's bedroom in the central area was assumed like as the Fig 7. and Fig 8.

The purpose of this study is to understand the architectural space of Gwolnaegaksa (闕 內各司), the Government office in the palace, in the early Joseon Dynasty. The Royal palace can be divided into three parts, political space for king, living space for king and his family and government office. So first, we should to understand the characteristics of each space in the Royal Palace. Up to now we have looked at the architectural space of Gwolnaegaksa in Gyeongbokgung (景福宮), one of the Royal Palace, the result of this study is as followings. There were not many Gwolnaegaksas in the early days in Gyeongbokgung. After King Sejong, some office buildings were established in that palace. King's closest guards, like as Seonjeonkwan (宣傳官), Gyumsabok (兼司僕), Naegeumwi (內禁衛) had been on duty in Sajeongjeon Haengrang (思政殿行廊), a kind of servants´ quarters. Bincheong (賓廳), a conference room of high-ranking government officials was situated in Geungjeon Haengrang (勤政殿行廊). There were also barracks of other palace guards in Geungjeon Haengrang. Gyeongyeoncheong (經筵廳), a place to prepare and wait, was built separately from Geungjeon Haengrang Layout drawings of Gyeongbokgung painted since the 18th century were different from document in some parts. The arrangement of the Gwolnaegaksa was assumed like as the Fig. 9.

The purpose of this study is to understand the architectural space of Seungjeongwon (承政院), the Royal Secretariat, in the early years of Joseon Dynasty. The Royal palace can be divided into three parts, political space, living space for king and his family and offices for government official in the palace. So first, we should to understand the characteristics of each space in the Royal Palace. The result of this study is following. Seungjeongwon of the Joseon Dynasty was where Seungji (承旨), Juseo (注書), Sagwan (史官), Seungjeonsaeg (承傳色), Seori (書吏) and Harye (下隷) worked together. The architectural space of Seungjeongwon was separated into Jeongwon-Cheong (政院廳) and Juseo-Cheong (注書廳). Jeongwon-Cheong was the office for Seungji, where Sagwan worked as well as Seungji and Juseo. The form of Jeongwon-Cheong (政院廳) in Kyung-bok Palace was similar to that depicted in Eundaegyecheop (銀臺契帖), which was painted the meeting of Seungjis. Juseo-Cheong was the office for Juseo and Sagwan and there was a break room. Apart from Jeongwon-Cheong there were rooms where Seungji could work or take a rest. As with the office of Seungji, the space for Juseo also had rooms for Juseo. There were also rooms for Seori and Abang (兒房) which were rooms for servants.

In this paper, we have studied Sogyupyo (小圭表, small noon gnomon) of the Joseon dynasty. According to the Veritable Records of King Sejong (世宗, 1418 - 1450), Daegyupyo (大圭表, large noon gnomon) with a height of 40-feet [尺] was constructed by Jeong, Cho (鄭招) and his colleagues in 1435, and installed around Ganuidae (簡儀臺, platform of Ganui). On the contrary, the details of Sogyupyo are unknown although the shadow length measurements by Daegyupyo and Sogyupyo are found on the Veritable Records of King Myeongjong (明宗, 1545 - 1567). By analysing historical documents and performing experiments, we have investigated the construction details of Sogyupyo including its development year, manufacturer, and installation spot. We have found that Sogyupyo would be manufactured by King Sejong in 1440 and placed around Ganuidae. And Sogyupyo would be five times smaller than Daegyupyo, i.e., 8-feet. On the basis of experiments, we suggest that although it is smaller, Sogyupyo was equipped with a bar [橫梁] and a pin-hole projector [影符] like Daegyupyo in order to produce the observation precision presented in the Veritable Record of King Myeongjong.

Since the thirteenth century, large scale facilities and various instruments for astronomical observation were built and installed in East Asia. During the Yuan Dynasty, S. ti.ntai (Beijing astronomical observatory in the Yuan Dynasty, 司天臺) was built in Beijing in 1279. Various astronomical instruments, including Ganui (Jianyi, simplified armillary sphere, 簡儀), Yang-yi (upward hemisphere, 仰儀) and Gyupyo (gnomon, 圭表) were installed in this observatory. These astronomical instruments were modified and improved by researchers of the Joseon Dynasty. Ganuidae (Joseon astronomical observatory, 簡儀臺) was built in Gyeongbokgung (or Gyeongbok palace, 景福宮), Seoul. Its scale was 31 Cheok (Korean feet in the Joseon Dynasty, 尺) in height, 47 Cheok in length and 32 Cheok in width. Lee, Cheon (李蕆, 1376~1451), a responsible leader of Ganuidae project, set up various astronomical instruments with his colleagues. Ganui and Jeongbangan (direction-determining board, 正方案) were installed at the top of this observatory. Gyupyo was installed at the west side of this observatory and Honui (armillary sphere, 渾儀) and Honsang (celestial globe, 渾象) were installed in a small pavilion which was located next to Gyupyo. A decade after installation, this observatory was moved to the north-west side of the palace but almost destroyed during Japanese invasion of Korea in 1592 except Ganuidae. We have analyzed documents about Ganuidae and investigated Chinese remains of astronomical observatories and artifacts of astronomical instruments. In this paper, we suggest the appearance, structure, arrangement and scale of Ganuidae, which are expected to be used for the restoration of Ganuidae at some day in the near future.
