The background that you see atop the Pentecostal Blogger site is a portion of the colosseum at Antioch. It has long since run into decay and is a mere ruins now. At this city, according to the bible, we find that the followers of Jesus Christ were first called Christians. The following excerpt from wikipedia was taken June 3rd, 2010 at 0003 Hawaii time.
The new city was populated by a mix of local settlers that Athenians brought from the nearby city of Antigonia, Macedonians, and Jews (who were given full status from the beginning). The total free population of Antioch at its foundation has been estimated at between 17,000 and 25,000, not including slaves and native settlers. During the late Hellenistic period and Early Roman period, Antioch population reached its peak of over 500,000 inhabitants (estimates vary from 400,000 to 600,000) and was the third largest city in the world after Rome and Alexandria. By the 4th century, Antioch’s declining population was about 200,000 according to Chrysostom, a figure which again does not include slaves.
