Résumé :
[The Renewal of the Byzantine Tradition in 16th-Century Greek Illustrated Oracle-Books] The article attempts to raise certain fundamental questions about the study of thirty 16th-century illustrated manuscripts, which contain the Oracles of Leo the Wise (PG 107, 1129-1140). It is shown that some of these manuscripts are congruent both in meaning and in style with corresponding western (mainly Italian) manuscripts, and also with representations that at first glance seem unrelated, which promoted the ideology of Renovatio Mundi. The type of these specific shared meanings, as well as the lasting, strong contrast between tradition and the present, which the Greek oracle writers were required to deal with, explain the iconographical choices and the stylistic idiom of the representation of oracles to a great extent.
