Quotes

 * I have seene sometimes two thousand Turkes travelling to Mecha, in Pilgrimage; which is in Arabia felix: where many in a superstitious devotion, having seene the Tombe of Mahomet, are never desirous to see the vanities of the World againe: For in a franticke piety they cause a Smith to pull forth their eyes: And these men are called afterward Hoggeis, that is, Holy men, whom the Turkes much honour, and regard: and are alwayes led about from towne to towne by mens hands, and fed, and regarded like unto Princes; or like the Capushines that scourge themselves on good Friday, met, and homaged at every passing Streete, with prayers, gifts, and adorations.
 * William Lithgow, Totall Discourse, IV, 150
