Claudia XIV. Philippe VII. Crevenna 1523. Hain 13066.

Leonardo Bruni, often called Leonardo Aretini from his birthplace
Arezzo, translated five of the dialogues of Plato in addition to the
letters.

The first notice of this edition is found in the _Catalogue
Bolongaro-Crevenna_ (Amst., 1789), where it is described as containing
52 printed leaves. It appears from the price-list printed after the sale
in 1790 that it had not been sold, but was "retenu, faute de commissions
ou de concurrence," and was still obtainable at the price of 15 florins.
No trace of it has since been found and Panzer and Hain were able only
to copy the catalogue description. Philippe (1885) described Heynlin's
copy, which is preserved in the library of the University of Basel, as
consisting of one first blank leaf, forty-nine printed leaves and two
blank leaves at the end. Claudin (1898), with a second copy discovered
meantime in the Bibliotheque d'Angers at his command, finds one first
blank and forty-nine printed leaves, and remarks that the two blank
leaves placed by Philippe at the beginning [should be _end_] are only
independent fly-leaves. Our copy has fifty-two printed leaves and no
blanks and no occasion for them, since the printed leaves, of
themselves, form complete quires. Claudin's collation, which gives both
the quires and a register of the first words of each quire, shows that
both his copies lack the sixth quire of our copy, composed like the
seventh of only two leaves and beginning "_sibus interdixistis_." There
is moreover still unexplained and not easily explainable in the
descriptions of both the Basel and Angers copies the presence of a
troublesome first blank leaf and the absence of another leaf of text, in
addition to the lacking sixth quire. It follows that, at least until the
Crevenna copy, which appears to have been in agreement with ours, comes
to light again, this must remain the only complete copy known.

Bound with Nos. 19 and 20, from the same press.
