The drawing recto obviously recalls a classical attitude. Filippino has followed, in reverse, the pose of a Roman sculpture of the Antinous type from the second century A.D. which was derived from Polycletus' famous bronze Doryphoros. This suggests a date about 1488-89, soon after Filippino's arrival in Rome.
The study verso seems to depict a boatman with a pole. The shading with short, prarallel strokes is very close to the technique on the verso of no. 1006, for which a date 1483-1488 has been proposed [Bjurström, It. Drawings, cat. no. 1015]
