We know the symbol from coins struck by cities on Sicily. However, I happened upon this from Wikipedia: On a mirror from Tuscania (E. S. 1. 76), Nethuns is represented talking to Uśil (the sun) and Thesan (the goddess of dawn). Nethuns is seated on the left, holding a double-ended trident in his right hand and with his left arm raised as if giving instructions. https://en.wikipedia.org/wiki/Neptune_(mythology) Thoughts?
