From the CNG description of a similar denarius: "In the Temple of Vejovis in Rome there stood near his statue another statue of a goat with a winged Genius on its back, which alludes to the infancy of Jupiter, who, on Mount Ida, was nursed by the goat Amaltheia. The caps of the Dioscuri are placed above, because they were worshipped at Tusculum, from where the Fonteia family originated."
