openings (e,f) were made in the partition-wall, either because the light was found to be deficient, or because it was thought best to throw the two rooms into one as far as possible. At some subsequent date the door (d) was blocked up, and the opening next to it (e) was carried down to the ground, so as to do duty as a door. The other opening (f), about 7 ft. 6 in. square, remains as constructed.
In one of Platina's memoranda quoted above, under date 7 June, 1476, "five large windows and two of smaller size" are mentioned; and, in the more detailed account which follows, the cost of the latter is set down as "pro duabus fenestris etiam magnis quæ vergunt ad curiam." I conceive that in this memorandum Platina is referring to the Latin and Greek Libraries taken together. The "five large windows" are the three in the north wall (B, C, D), and the two in the west wall (b, c); the "two of smaller size looking into the court" are the window at the south end of the Greek Library (E), and that over the door of entrance (A). Four doors are mentioned in the same memorandum. It is not easy to identify these. The door of entrance (A) and the door into the Greek Library (d) are certainly two of them; the other two may be the door between the Greek Library and the Bibliotheca Secreta, and the door into the Librarian's room (a); or that door and the door into his room from the court.
The decorative work of the brothers Ghirlandajo can still be made out, at least in part, though time has made sad havoc with it. The edges of the vaulting were made prominent by classical moldings coarsely drawn in a dark colour; and at the key of each vault is a large architectural ornament, or coat of arms, surrounded by a wreath of oak-leaves and acorns, to commemorate the Della Rovere family. They are tied together on each side with long flaunting ribbons, which, with their shadows, extend for a considerable distance over the vaults. The semi-circular lunettes in the upper part of the wall under the vaults, are all treated alike, except that those on the sides of the room, being larger than those at the ends (fig. 2), contain two subjects instead of one. The lower part, for about 3 feet
