Ludwich assembled a list of all the lines put forward as quotations from Homer in pre-Alexandrine authors: some 29 authors plus some unknown fragments, amounting to about 480 "verse", or “lines.” D.B. Monro used this database to compare the percentage of non-Vulgate lines in the quotes with a control group, the non-Vulgate lines in the fragments of the papyri known to him then. Judging from the fragments, 60 of the 480 lines ought to be missing from the Vulgate. The number is only 12, from which Monro concludes: “The quotations, in short, prove that there was a pre-Alexandrian vulgate agreeing much more closely with the modern vulgate than with any text of which the papyrus fragments can be specimens.”
