Unknown God
The Unknown God or Agnostos Theos (Ancient Greek: Ἄγνωστος Θεός) is a theory by Eduard Norden first published in 1913 that proposes, based on the Christian Apostle Paul's Areopagus speech in Acts 17:23, that in addition to the twelve main gods and the innumerable lesser deities, ancient Greeks worshipped a deity they called "Agnostos Theos"; that is: "Unknown God", which Norden called "Un-Greek". In Athens, there was a temple specifically dedicated to that god and very often Athenians would swear "in the name of the Unknown God" (Νὴ τὸν Ἄγνωστον, Nē ton Agnōston).
