Note 2 — Chapter IV
Reading edition
This, the first mosque built at Cairo, is said to have been paid for by Sultan Tayloon with a part of an immense treasure in gold, which he found under a monument called the altar of Pharaoh, on the mountain of Mokattam. This building was destroyed by Tayloon, who founded a mosque upon the spot in the year 873, in honour of Judah, the brother of Joseph, who resorted there to pray when he came to Egypt. This mosque becoming ruined, another was built upon the spot by the Emir El Guyoosh, minister of the Caliph Mostansir, A.D. 1094, which still remains perched on the corner of a rock, which is excavated in various places with ancient tombs.
