This clock is modelled as Minerva and features the attributes of the war goddess. Among such elements, the plumed helmet and the aegis or skin breastplate centred by the mask of Medusa, the serpent-haired creature whose head was presented to Minera by Perseus after he slained the monster.
Such martial or warrior-inspired models are recurrent in the Empire period and further examples featuring the Goddess of War include a clock in the château de Malmaison (ill. B. Chevallier et al., Napoléon, exh. cat., Memphis, 1993, cat. 56. p. 71).
