John Phokas
John Phokas may have been the author of Ekphrasis (or Concise Description) of the Holy Places which Ambraseys (2009)
refers to as Descriptio Terrae Sanctae. This text was reproduced in an English translation as "The Pilgrimage of Johannes Phocas in the Holy Land (in the year 1185 AD)" by the
Palestine Pilgrims' Text Society.
