Christmas in the Qur'än: the Qur'änic account of Jesus's nativity and Palestinian local tradition
http://www.academia.edu/1057321/Christmas_in_the_Qurän_the_Quränic_account_of_Jesuss_nativity_and_Palestinian_local_traditionIn winter of 1997, an archaeological discovery occurred on the outskirts of Jerusalem, holding great significance for our understanding of the earliest development of the Qur ̄anic traditions. Approximately halfway between Jerusalem and Bethlehem, just to the east of the main highway, a group of archaeologists from the Israel Antiquities Authority engaged in a salvage operation unearthed a large octagonal church, which our late ancient sources identify as the church of the “Kathisma of the Theotokos,” or the “Seat of the God-Bearer.” As the present article will demonstrate, this church was originally associated with the Nativity of Christ, but eventually came to be linked with the commemoration of Mary’s death and, more importantly, with certain events from the Holy Family’s legendary flight into Egypt, as described in several early Christian apocrypha. The new church’s connection with both Christ’s Nativity and the flight into Egypt is particularly important, since it is (to my knowledge) the only place where these two early Christian traditions meet, outside of the Qur ̄anic account of Jesus’ Nativity. There is a great deal more, however, than just this mere coincidence to suggest that traditions associated with this shrine influenced the development of early Islamic tradition. The church of the Kathisma was converted into a mosque in the early eighth century, and its mosaics indicate that the recycled sacred space probably continued to commemorate the Nativity of Jesus, as the Christian shrine had before the Arab conquests. Moreover, the significance of this shrine in early Islam is underscored by the important architectural and artistic relationships that scholars have identified between the Kathisma church/mosque and the Dome of the Rock....
