This paper attempts to trace T. S. Eliot’s thoughts on Lancelot Andrewes. Readers have thought little of Andrewes’s fame until Eliot wrote on him, thinking of him as only a prominent writer or preacher. But surprisingly Eliot in “Andrewes” compares Andrewes’s writing method with Donne’s. The paper suggests many ways Andrewes influenced Eliot. Eliot attributes to Andrewes’s writings three qualities ―1) ordonnance or arrangement and structure, 2) precision in the use of words, 3) relevant intensity.Eliot says that Dante in his Divine Comedy succeeds in harmonizing intelligence with emotion properly. Similarly, Eliot holds that the internal structures correspond to the external ones in Andrewes’s sermons. We can see influences from Andrewes’s sermons in Eliot’s “Gerontion” and Ash-Wednesday. Especially Eliot emphasizes that Andrews uses the phrases easy to remember. Eliot views Donne as continuously seeking for objects suitable for his emotions, and Andrewes as after the ones to express his self, not his own self. Thus Eliot finds Andrewes “wholly absorbed in the object.”
