putting a crown on St. Catherine's head; while the Mother holds another in her hand, in order that the B. Marco may be crowned by her in his turn. Two angels form the train, one of whom points to the wheel, a symbol used by the saint, and indeed touches with his finger a sharp point, the better to give an idea of the sufferings of her martyrdom. The other is an Angel of the Apocalypse, with book and sword; a figure well suited to the last judgment, whose terrors the B. Marco inculcated in his sermons. There are two other beautiful cherubs, which add to the interest; one standing near St. Catherine, holds a roll of Egyptian papyrus, with some Coptic characters, in which were described the acts of her passion; while his companion points the attention of the spectator to a maxim continually repeated by the B. Marco, "Nolite diligere mundum," inscribed upon marble. How widely different, in point of invention, appears an artist versed in literature, and one with no taste for letters! This, however, is not the whole merit of such a painting: the saint and one of the angels are truly Raffaellesque figures; the Beato in extasy, brings to mind the B. Michelina of Baroccio; the other figures are all exceedingly well studied, and seem intended to display the artist's refined gratitude towards his patrons. Footnote 53: These paintings, executed in the abside of the cathedral, with the assistance of his pupils, constitute his most celebrated frescos. In this "Account" there is a Discourse, well worth notice, on Ancient Marbles of different Colours, which he introduced in those paintings, and the method he adopted in uniting them. Such a treatise, not to be found in any other writer, renders this little volume valuable; which shews, too, that he likewise excelled in architecture. Footnote 54: These Treatises were published at Pesaro in 1806; and, although, as the industrious editor well observes, they were drawn up from unfinished sketches, they still gratify us, no less by their extensive information, than by the ingenuity which they display.
