Aurispa already owned the "two volumes" in 1421; this suggests that he may have brought them back from a trip to Greece in 1413. For a long time it was thought that these two volumes were Venetus A and Venetus B. More recently, however, it has been pointed out that the Venetus A and B manuscripts list multiple authors as their sources, not just Aristarchus, and Aurispa would be unlikely to have ignored this distinction. One scholar has suggested that Aurispa's two volumes were in fact Laurentianus LIX 2 and 3, a two-volume copy of Eustathius' "Iliad" commentary corrected in Eustathius' own hand, and in which the title is erased.
