Boarding Gate 101

Predominantly used during medieval times in cathedrals and churches, stained glass windows to evoke grandeur as well as to tell stories to the observer, usually biblical ones.  The techniques to created stained glass were described by a 12th century German monk, Theophilus, in his book On Diverse Art . The use of stained glass became prevalent between 12th and 16th centuries.

This is a book that's familiar, as this is a topic of my philosophy and social science classes in the university: Saint Augustine's City of God .  The book on display at the Metropolitan Museum of Art is one of the three volumes of the Spanish translation made by Cano de Aranda for the bishop of Toledo. The book is made of parchment, tempera and gold leaf.
