Saint Helena ( Latin : Flavia Iulia Helena Augusta ) also known as Saint Helen , Helena Augusta or Helena of Constantinople ( ca . 246/50 – 18 August 330) was the consort of EmperorConstantius , and the mother of Emperor Constantine the Great . She is traditionally credited with finding the relics of the True Cross , with which she is invariably represented in Christian iconography.
She selected some town and called it Nazareth. She also selected the mountain most xians accept as Mt Sinai.
According to Eusebius of Caesarea she was responsible for the construction or beautification of two churches, the Church of the Nativity, Bethlehem , and the Church on the Mount of Olives , sites of Christ's birth and ascension. Local founding legend attributes to Helena's orders the construction of a church in Egypt to identify the Burning Bush of Sinai. The chapel at St. Catherine's Monastery --often referred to as the Chapel of Saint Helen—is dated to the year AD 330.

During the Byzantine period, Nazareth became a holy place for Christians and its first church was built over a cave where Joseph and Mary are believed to have lived. In this period, there was also a large increase in pilgrimage to Nazareth . Towards the end of the Byzantine era, Jewish settlement in Nazareth came to a halt and the city became Christian.
As always dont believe a single thing i say, do your own research and you will find many intersting similarities..Notice the theme of the Flavian connection with xianity...Its the family business, while other caesars ignored xianity the flavians continued to be a part of its earlies history.
