The present sculpture falls within a specific category of sleeping erotes classified as the Bergamo-Vienna type, which is represented by seven other known examples (see M. Söldner, Untersuchungen zu liegenden Eroten in der hellenistischen und römischen Kunst, Frankfurt am Main, 1986, vol. 2, pp. 638ff., cat. nos. 77-83). For a related related example in the Museo dei Conservatori in Rome, inv. no. 936, see H. Stuart Jones, The Sculptures of the Palazzo dei Conservatori, Oxford, 1926, p. 88, no. 25, pl. 32 (http://arachne.uni-koeln.de/item/objekt/26194).

The two versions thought to be closest to the original Hellenistic prototype are in a private collection in Bergamo and in the Kunsthistorisches Museum, Vienna, inv. no. I 1426 (K. Lange, Der Schlafende Amor des Michelangelo, Leipzig, 1898, illus. p. 22 and fig. 2, respectively). Another example, once at Whitehall in London (see the late 17th Century drawing in Lange, op. cit., p. 52, upper left corner) is thought to have to have been lost in a fire and might have been the famous fake Sleeping Cupid created by Michelangelo in 1496 when he was 20 years old. Yet another version once thought to be Michelangelo's creation, this one clearly not ancient, is in Turin (see Lange, op. cit, p. 19, and C.M. Brown, "The Erstwhile Michelangelo Sleeping Cupid in the Turin Museo di Antichità," Journal of the History of Collections, vol. 5/1, 1993, pp. 59-63).
