CCCC MS 81 is a large and handsomely decorated paper manuscript of the mid-fifteenth century, copied by Demetrios Xanthopoulos, who worked in the circle of Cardinal Bessarion (1403-72). It contains Homer, Iliad, Quintus of Smyrna, Posthomerica and Homer, Odyssey. There are intermittent Homeric scholia in the hand of Demetrios Chalkondyles, the scholar who supervised the production of the editio princeps of Homer in 1488; some of the scholia on Odyssey yield new textual evidence. A circular cartouche on p.1 with the name 'Theodoros' in gold letters is probably a sign of Theodore Gaza's (c.1400-1475) ownership, but may have led to the belief that the book (along with CCCC MSS 224 and 248 and six other Cambridge MSS) came from Theodore of Tarsus (602-690). Notes by Parker and others suggest that the book was found at Canterbury, possibly as part of the library of St Augustine's Abbey.
