The paper discusses some questions conserning spreading of one of the most popular cults of the Roman Empire - Egyptian Jsis - being at first a classical example of Hellenistic and then Roman religious syncretism.
Based on the studies of a given problem, we arrived at a conclusion, that cult of Egyptian goddess was basically spread in eastern regions of the Roman Empire and in the centre of Latina. In eastern provinces, particularly in Greece and Near East (Antioche, Tarce, Syria) Egyptian cults emerged at the beginning of Hellenistic period. In 307 Egyptians had cult of Jsis in Halicarnace and in the cities of Carie.
We don't exclude, that prior to Roman period, Alexandrian goddes was common in Colchians, as well cults were not alien to Colchians, and the whole Hellenistic world. In the religious beliefs of West Georgia Magna Mater had a particular place, being a member of wide hypostases of Jsis-Osiris, Astarta-Melkart, Kibela-Atis. Jsis is characterised with religious syncretism. Some scientists identify Jsis with Hecata, considering Colchis her native country.
In western provinces Alexandrian goddess was mostly spread in Spain, in Northern and North-West provinces of the Roman Empire the credit for spreading cult of Jsis goes to Romans, but Alexandrian goddess was not popular here. In Gallia Jsis was popular basically among city population.
As to the centre of the Roman Empire - Latina - cult of Jsis was brought to Italy since the end of republican period, Alexandrian goddess emerged in Sicily prior to that. Italian merchants brought its cult from Delos to Campanie. In the 2nd century B.C. it was already worshipped in Herculanum, Puzzole, Etruria, Pompei.
From the 1st century A.D. Alexandrian goddess became favourable for Roman emperors. Cult of Jsis was at its height during the reign of Caracallus and Septimius Severus. In the struggle against Christianity Jsis was losing its position. During the reign of the first Christian emperors cult of Jsis was reduced to standards of a pagan sect, that eventually led to abolition of Alexandrian goddess.
