Described in a letter by Dr. Lodovico Pollak, dated August 16, 1941, who states that the figure was found in the lagoon of Venice. The presence of marine incrustations supports this claim.
For a related pantheistic deity in the Birmingham Museum and Art Gallery see no. 279 in Canciani, "Iuppiter" in LIMC. The Birmingham deity differs in that he holds a caduceus in one hand, a cornucopia topped with a bust of Minerva in the other, and the plume of the helmet is surmounted by a bust of Zeus. Compare also the bronze statue of a Genius from Weissenburg, no. 13 in Kellner and Zahlhaas, Der Römische Tempelschatz von Weissenburg i. Bay. The Weissenburg figure holds a thunderbolt and cornucopia. In place of a helmet he wears a crenellated crown but with a similar crest.
