While at a monastery at this physical location, Constanin von Tischendorf allegedly rescued a discarded manuscript which is now grouped with Alexandrinus and Vaticanus among the four great uncial codices. That monastery at this site features the world's oldest operating library, the oldest Pantocrator icon, and the relics of a saint sentenced to execution by breaking wheel. A man wears a veil to cover his shining face after returning from this place a second time. This site of Saint Catherine's Monastery is usually equated with Horeb. After his first return from this place, a man makes his (10[1])people (10[1])drink water mixed with gold from an idol which he (10[1])destroys (10[1])after angrily smashing two stone tablets. For 10 points, name this mountain beneath (10[1])which the Israelites made a golden calf (10[1])while Moses (10[1])first received (10[1])the (10[1])Ten Commandments. ■END■
