The basis for thinking of Jerusalem as the center of the world had been established centuries before the time of Constantine. The prophet Ezekiel had spoken of Israel, and by extension Jerusalem, as “the center of the earth” (Ezekiel 38:12) at a future time under the rule of the Messiah. In the Greek rendering of the Hebrew Scriptures, this was translated as omphalos - navel. The first-century Jewish historian Flavius Josephus, who wrote in Greek, referred to Jerusalem in the same manner (Wars of the Jews).
Jewish thinking believed that the Temple Mount was the first part of God’s creation as well as the site of Adam’s creation. Such beliefs were complemented by Christian ideas that Adam had also been buried at Golgotha and was interred beneath the Church of the Holy Sepulcher. Several centuries later, when Muslims laid claim to Jerusalem, they adopted similar ideas as to the importance of Jerusalem in the order of creation as part of their own justification for the religious significance of the site.
