Sianna(Stanna) is a Romano-celthic goddess from Roman Gaul, attested epigraphically from Vesunna (novaday Perigieux), which is close related with Roman goddess Dianna. The goddess Sianna is attested by an inscription composed of five fragments discovered in the buildings of the ‘Vieilles Casernes’ in Périgueux (Dordogne), in the territory of the Petrocorii, where she is partnered with the god Telo. Thanks to the comparison of the various fragments, the suggested restoration is certain, except for the end of the first line and the beginning of the second line: Deo Telo et deae Stannae, solo A(uli) Pomp(eii) Antiqui, Per…ius, Silvani fil(ius) Bassus, c(urator) c(ivium) r(omanorum), consaeptum omne circa templum et basilicas duas, cum ceteris ornamentis ac munimentis, dat, ‘To the god Telo and to the goddess Sianna, Per[…]ius Bassus, son of Silvanus, curator of the Roman citizens, offers, at his own expense, this entire wall erected around their temple on the land of Aulus Pompeius Antiquus, and these two basilicas with the other embellishments and accessories’.2086 This inscription is of great interest, for it mentions the existence of a temple dedicated to Telo and Stanna. The dedicator Per[…]rius Bassus is a Roman citizen and holds official functions. He is a curator, which means he had been appointed by the emperor to manage and supervise the finances of the city. He offers a wall, two basilicas, ornaments and accessories extending and embellishing the sanctuary, which is built on the property of the Roman citizen Aulus Pompeius Antiquus. Sianna and Vesunna are two goddess from town Perigieux on the territory of Petrocoria.
