Goats and cockerels are the cult animals associated with the god, Mercury and they may have been intended to stand on pedestals flanking Mercury figurines. An almost identical goat figurine is known from the Uley shrines, Gloucestershire – thought to be dedicated to Mercury on the basis of the significant quantity of religious objects associated with that god and discovered there during excavations.
Astoundingly, the chance find of this figurine was accompanied by that of a figurine of a cockerel, which is almost undoubtedly connected.
