'The Anointed One', Hellenic title of Jewish Messiah.
The Christ of the New Testament is now widely regarded to be a mythical figure (though many Christians still deny this), based on a number of fertilty gods and Mystery Religions.
This mythification appears to have been initiated by the Hellenized Jew Saul of Tarsus (later known as St Paul). Who sought to create a new pro-Roman religion from the militant Jewish sect of the Nazarenes.
The historical basis for Christ was an obsure messianic Rabbi variously known as Issua or Joshua ben Miriam. About who little is known, outside of the general trend of Roman resistance and Judaic fundamentalism.
