Potrimpo

thumb|The purported Flag of Widewuto (Potrimpo on the right) Potrimpo (also Potrimpus, Autrimpo, Natrimpe) was a god of seas, earth, grain, and crops in the pagan Baltic, and Prussian mythology. He was one of the three main gods worshiped by the Old Prussians. Most of what is known about this god is derived from unreliable 16th-century sources.

He was first mentioned (as Natrimpe) in a 1418 memorandum Collatio Espiscopi Varmiensis sent by the Bishop of Warmia to Pope Martin V. The document reminded the Pope that the Teutonic Knights successfully Christianized pagan Prussians, who previously worshipped "demons" Perkūnas, Potrimpo and Peckols (and Patollo). Simon Grunau claimed that Potrimpo was a god of grain and together with thunder god Perkūnas and death god Peckols formed a pagan trinity. He was depicted on the purported Flag of Widewuto as a young, merry man wearing a wreath of grain ears. Grunau further claimed that snakes, as creatures of Potrimpo, were worshipped and given milk (cf. žaltys). The Sudovian Book (1520–1530) listed Potrimpo (Potrimpus) as god of running water and Autrimpo (Autrimpus) as god of the seas. The Constitutiones Synodales, a church ceremony book published in 1530, likened Potrimpo with Pollux and Autrimpo with Castor and Neptune, from Roman mythology.
