Dius Fidius

Dius Fidius is considered a theonym for Jupiter, and sometimes a separate entity also known in Rome as Semo Sancus Dius Fidius. Wissowa argued that while Jupiter is the god of the Fides Publica Populi Romani as Iuppiter Lapis (by whom important oaths are sworn), Dius Fidius is a deity established for everyday use and was charged with the protection of good faith in private affairs. Dius Fidius would thus correspond to Zeus Pistios. The association with Jupiter may be a matter of divine relation; some scholars see him as a form of Hercules. Both Jupiter and Dius Fidius were wardens of oaths and wielders of lightning bolts; both required an opening in the roof of their temples.
