Should you chance, in crossing a certain mountain pass in southern Catalonia, to find yourself poised above a little valley against the opposite side of which lies a monastery, look to the heights above it. Should you piece out from among the rocks the jagged ruins of a castle, ask its name. Your guide will perhaps inform you that those blackened stones are called "The Teeth of the Moor," and if he knows the story he will doubtless tell it to you, crossing himself many times during the recital. In all probability, however, he will merely shrug his shoulders and say it is a place of bad repute, nothing more. Even the monks of the monastery, who are considered well versed in local history, have forgotten the reason for the name, although they recall the legend that once upon a time the castle harbored a haughty Moslem lord. Few of them ever heard the story of Joseph the Anchorite, and how he sought flesh within its portals; those who have will not repeat it. Time was, however, when the tale was fresh, and it runs this wise: Away back in the reign of Abderamus the Just, First Caliph of the West, Hafiz, a certain warlike Moor, amazed at the fertility of this region, established on the edge of the plateau a stronghold of surprising security. His house he perched upon the crest of the cliff overlooking the valley below. It was backed by verdant, sun-kissed slopes which quickly yielded tribute in such quantity as to render him rich and powerful. Hafiz lived and fought and died beneath the Crescent banner, leaving in his place a son, who likewise waged war to the northward on behalf of the Prophet and all True Believers, at the same time farming his rich Catalonian acres.
