III).

The dates of these codices (centuries indicated by Arabic numerals)
are about as follows:

I. Mediceus A-Ma- (11)
I. Venetus A-Va- (11)
I. Vaticanus A (15)
I. Parisinus A (17)
II. Mediceus B (15)

III. Venetus B (15)
III. Vaticanus B (15)
I. and III. Vesontinus (15)
III. Turinensis (16)
III. Escorialensis (?)
I. Codex Vaticanus græcus No. 1288 (5-6).
