According to Vermeule and Eisenberg (op. cit.), "the subject is very rare, if not unique, in bronze and is better paralleled in Pompeiian painting or in so-called Campana and other terracotta architectural plaques. This ensemble anticipates the various adventures of Eros, with and without Psyche, on Roman marble sarcophagi of the Second and Third Century A.D. The architectural plaques and the lids of sarcophagai usually show such Erotes in their boats on the river Nile."
