More than any other cult of the Roman world, the worship of Theos Hypsistos has been taken to illustrate the predisposition among pagans of the second and third centuries AD to worship a single, remote, and abstract deity hidden behind the appellatives Zeus Hypsistos, Theos Hypsistos or Hypsistos, in preference to the anthropomorphic figures of conventional paganism.

This study emphasizes the connection of the Theos Hypsistos worshippers within the Balkan provinces of the Roman Empire and their linking with the Greco-Roman religious system. Furthermore, we will analyse the archeological and the epigraphic evidence for Theos Hypsistos in the main centres where this cult is found. Another aspect that will be shown are the close relations between the Jewish groups and Theos Hypsistos.

The Balkan provinces of the Roman Empire have some important centres of Hypsistos cult, Godfearers, and Jewish Communities outside Palestine. The aim of this papper is to present the relations between cults mentioned above, and for this we will make a travel in each important center, from Beroaea and Thessalonica to Oescus, from Selymbria to Tomis. Another important point of this presentation is the chronology of the cult, from the 2nd century B.C to 3rd century C.E, the rise and the slow decline of the cult centres.

Last but no least, we will analyse Dacia, as the northern province from Balkans where the cult of Theos Hypsistos is found.
