Its dating to 1488–1490 is based on Giorgio Vasari's description of Francesco I de' Medici's collections, which attributes it to Mantegna's time in Rome. Some have linked it to a work commissioned from Mantegna by Lorenzo de' Medici and mentioned in a letter from Lorenzo. Other historians date it differently due to its style and figuration. However, Mantegna's re-use of certain themes like rocky backgrounds throughout his career makes it difficult to date uncertain works definitively.
