Trumusiatis (Venetic trumusijatei, with the variant Tribusiatis) is the presiding god of the mountain spring-sanctuary of Làgole di Calalzo, high in the Cadore on the upper Piave, which produced nearly a quarter of all known Venetic inscriptions. Worshippers came for the curative sulphurous waters, which they drew with bronze ladles (simpula); after drinking or washing, the ladle was deliberately broken and its inscribed handle, carrying a short votive formula with the dedicant's name and the god's name and epithet, was deposited as a gift. He is regularly given the epithet sainate, the same word attached to Reitia at Este; once read as 'the healer', it is now often taken as a 'poliadic' title marking the god of the place, since it recurs at Este and Altino. In the Roman period the god of Làgole was syncretised with Apollo, who appears by name on the later inscriptions of the site.
