A drawing of a Roman priest standing beside an altar, about to pour a libation. A soldier and other figures kneel before the altar, and above Fame and a putto carry a coat of arms surmounted by a coronet (? ducal). A radiant sun appears on the altar and elsewhere in the design, and bees appear at several points.

The bees and the sun, which are much used as a decorative motif on the Palazzo Barberini, indicate a connection with that family. This connection is confirmed by the style of the drawing, which suggests a classical member of the Barberini group, familiar with the early work of Cortona. Probably by the same hand as RCIN 990118. This is possibly a design for the title-page of a book.
