This clock evokes the virtue of constancy in love. Its laurel-wreathed altar, guarded by Venus' sacred swans, bears an inscribed tablet and a bas-relief of blindfolded Cupid, serving to warn against inconstancy. The trimming of the wings of Venus's dove by a maiden seated beside a garlanded and enflamed candelabrum, recalls the history of Venus and her lover Adonis. The bas-relief of its stepped plinth is inspired by Rome's Temple of Fortuna. With its candelabra and butterfly-bearing Cupids, the composition recalls the love story of Cupid and Psyche. Interestingly, the whole replaces the usual iconography of 'inconstancy' represented by the moon symbol of the huntress deity Diana, by supplanting it with Venus and Cupid.
