This veil-draped ”altar” clock is dedicated to Venus and celebrates Love’s dominion. Its pillar of a pearl-wreathed and orb-capped obelisk is embellished with a bas-relief of Hymen’s torch held by Cupid bearing aloft a globe borne by Venus’s attendant Graces. The plinth tablets reveal festive putti preparing for a sacrifice at Love’s altar. A clock of related model in bleu turquin marble, in the Louvre in Paris is illutrated in H. Lengellé, dit Tardy, French Clocks The World Over, Paris, 1981, vol. II, fig. 60. A similar obelisk mantel clock is also illustrated in P. Kjellberg, Encyclopédie de la pendule française du Moyen Âge au XXe siècle, Paris, 1997, p. 219.
