How popular this "scientific art" was in its day may be seen from the following enthusiastic account which Vasari gives of this picture:-- A remarkable and admirably executed work, with numerous horses, many undraped figures, and singularly beautiful foreshortenings. This picture likewise contains the portrait of St. Sebastian himself, taken from the life--from the face of Gino di Ludovico Capponi, that is. The painting has been more extolled than any other ever executed by Antonio. He has evidently copied nature in this work to the utmost of his power, as we perceive more particularly in one of the archers, who, bending towards the earth, and resting his weapon against his breast, is employing all the force of a strong arm to prepare it for action; the veins are swelling, the muscles strained, and the man holds his breath as he applies all his strength to the effort. Nor is this the only figure executed with care; all the others are likewise well done, and in the diversity of their attitudes give clear proof of the artist's ability and of the labour bestowed by him on his work; all which was fully acknowledged by Antonio Pucci, who gave him three hundred scudi for the picture, declaring at the same time that he was barely paying him for the colours. This work was completed in the year 1475. The dominant motive in the picture is, it will be seen, interest in the mechanism of the human body; notice especially the muscles of the executioners' legs and their efforts in stretching their bows. There are, however, other points worthy of notice. "The work is not less remarkable for the extent and variety of the landscape, and for the sense of aerial, as distinct from mere linear, perspective. Instead of standing up like a wall behind the figures it appears to recede to the horizon, as in nature. The study of the remains of classical art also is betrayed by the introduction of one of the Roman monumental arches in the background. The groups of soldiers and horses introduced at different distances further attest the variety of the designers' interests" (Monkhouse: _In the National Gallery_, 1894, p. 77). 293.
