Sancus
Usually called
Semo Sancus. (See
Semones.) A genius worshipped by the Sabines, Umbrians,
and Romans, representing holiness and good faith in human life. In Rome he was principally
worshipped under the name Deus Fidius (from
fides, “faith”) as god of oaths, god of the public laws of
hospitality and of nations, also of international intercourse and of the safety of the roads,
which were placed under his protection. An oath in his name could be taken only under the open
sky; therefore even his temple had a hole in the roof, and, when an oath by him was taken at
home, the man swearing went into the uncovered court. On account of many points of resemblance
he was identified with Hercules. He had a temple on the Quirinal (the foundation of which was
celebrated June 5th), and another on the island in the Tiber (Ovid,
Fasti, vi.
213-218).
