The Fourteen Amorini: a study of Cupid with Neptune's trident

A photograph of the verso of a red chalk drawing now in the Staatliche Kunstsammlungen, Dresden (inv.no.C161), where it is catalogued as by Raphael (c.1518). This drawing depicts a detail of the fresco in the vault of the entrance loggia of the Farnesina, Agostino Chigi's villa in Rome, which was frescoed with mythological subjects by Raphael's workshop c.1518. In the fourteen lunettes of the bays are Amorini or Cupids, with the attributes of the deities who have done homage to Love.
This is a study of Cupid with Neptune's trident. Ruland (1876) writes: "on the back of No 4, supra", identifying this drawing as the verso of the drawing reproduced in RCIN 853997. Annotated on the verso

The fresco decoration in the Farnesina illustrates the classical fable of Cupid and Psyche, a story which was also frequently used to decorate Florentine wedding chests. Raphael's fresco scheme comprises two primary scenes in the vault (painted to resemble tapestries), accompanied by a series of episodes painted in the pendentives. The whole is encompassed within a fictive pergola, which gives the viewer the impression of looking up into the heavens. Only the upper part of the loggia is painted (the vault and its supporting pendentives and spandrels).
