Recto: a drawing of a masquerader seated on a horse, which is walking in profile to the left. He wears a head like an elephant, with long ears, curling tusks and a trunk which doubles as a wind instrument. Verso: geometrical drawings of the lines of sight; a sketch of a round object with projecting squares at regular intervals; architectural drawings of a three-sided courtyard; two plans, an elevation, and two perspective drawings. The drawing is a study for the costume of a mounted masquerader, with an elephant's head, ragged ears, a curving trumpet on top of the head, long narrow wings hanging down from the shoulders, a pot belly, and a curly tail. A wind instrument is integrated into the trunk, and it is likely that the whole costume was a bagpipe, with the bag contained in the belly and the drone over the head.
