In the GALLERY OF APOLLO will be exhibited in succession, about twelve thousand original drawings of the Italian, Flemish, and French schools, the greater part of which formerly belonged to the crown. This valuable collection had been successively enriched by the choice of those of JABAK, LANQUE, MONTARSIS, LE BRUN, CROZAT, MARIETTE, &c. yet never rendered public. Private and partial admission to it had, indeed, been granted; but artists and amateurs, in general, were precluded from so rich a source of study. By inconceivable neglect, it seemed almost to have escaped the attention of the old government, having been for a hundred years shut up in a confined place, instead of being exhibited to public view. The variety of the forms and dimensions of these drawings having opposed the more preferable mode of arranging them by schools, and in chronological order, the most capital drawings of each master have been selected (for, in so extensive a collection, it could not be supposed that they were all equally interesting); and these even are sufficiently numerous to furnish several successive exhibitions. The present exhibition consists of upwards of two hundred drawings by the most distinguished masters of the Italian school, about one hundred by those of the Flemish, and as many, or rather more, by those of the French. They are placed in glazed frames, so contrived as to admit of the subjects being changed at pleasure. Among the drawings by RAPHAEL, is the great cartoon of the Athenian School, a valuable fragment which served for the execution of the grand _fresco_ painting in the Vatican, the largest and finest of all his productions. It was brought from the Ambrosian library at Milan, and is one of the most instructive works extant for a study. Besides the drawings, is a frame containing a series of portraits of illustrious personages who made a figure in the reign of Lewis XIV. They are miniatures in enamel, painted chiefly by the celebrated PETITOT of Geneva. Here are also to be seen some busts and antique vases. The most remarkable of the latter is one of Parian marble, about twenty-one inches in height by twelve in diameter. It is of an oval form; the handles, cut out of the solid stone, are ornamented with four swans' heads, and the neck with branches of ivy. On the swell is a bas-relief, sculptured in the old Greek style, and in the centre is an altar on which these words may be decyphered. [Greek: SOSIBIOS ATÆNAIOS EPOIEI.] _Sosibios of Athens fecit._ This beautiful vase[2] is placed on a table of violet African breccia, remarkable for its size, being twelve feet in length, three feet ten inches in breadth, and upwards of three inches in thickness.
