The present cast of the Sleeping Nymph is usually accompanied by the kneeling figure of an enthusiastic satyr. A larger, complete version was included in the London Giambologna exhibition (op.cit.) ascribed to Ferdinando Tacca. Originally, the group derives from Giambologna's sculpture of the same subject, but with several differences; primarily, the nymph's left arm is folded under her head and the chaise-longue is totally draped by a fringed shawl. A bronze cast of the nymph alone is in the Fitzwilliam Museum, Cambridge; but in the present example the attachment hole for the satyr is still visible. A larger version with the satyr present was sold in these Rooms, 3 July 1990, lot 83.
