In the profound teachings of the ancient Gnostics and the hermetic star-gazers, the visible cosmos is not a manifestation of the supreme, unutterable God, but the flawed creation of a lesser deity, the blind architect known as Yaldabaoth or the Demiurge.

To understand this cosmic architecture is the first step towards liberation; to map it is to forge the key to the prison door. The Astrolabe of the Firmament is the conceptual map of this celestial penitentiary. Unlike modern astronomical charts, which view the cosmos as an infinite, mechanis...

Part astronomical clock, part navigation device, part calculator, part model of the universe, the astrolabe could determine the time of day from the sun's position, find the altitude of stars, predict the positions of the planets, calculate the times of sunrise and sunset, and locate the direction of Mecca for prayer.

The astrolabes that survive from medieval Islam, al-Andalus, and Christendom are among the most beautiful scientific instruments ever made, their engraved celestial maps combining mathematical prec...
