"Horse-grooms feed herds of horses from the best of Arabia, wash them with fragrant wines, feed them with raisins and peanuts, hang necklaces around their necks with pearls, the marble stables are adorned with mosaics and the Imperial family with the whole of the Court and the congregation, was once forced to leave the Hagia Sophia. The service under the Patriarch ceased due to a sudden health problem of his favored mare.
