AD>The Monastery of Pantokrator, founded by John II Komnenos and his wife Piroska-Irene, is not only one of the most important and most impressive monastic complexes of the Komnenian age, it is also one of the few to occupy a key position in the life of Constantinople in the Palaiologan age,given that itsmortuary chapel (Heroon) was also the last resting place of many members of the latter dynasty. The first attempt to chronicle its history, based on the texts known at the time, was undertaken by G. Moravscik (1932). Interestwas rekindled by P. Gautier¿s critical edition of its Typikon (1971), and more recently by restoration work on its buildings. This volume brings together a comprehensive selection of all the texts concerning or connected with the Monastery of Pantokrator, and through themit demonstratesthe Monastery¿simportance and its role throughout the history of the Byzantine Empire¿a role that has received insufficient attention, given that older studies have tended to focus on the 12th century. The texts cover the situation in Constantinople before the Monastery was founded, the historical and cultural context within which it was established, its Typikon (monastic formulary), the descriptions of Slav and Western travellers, the Byzantine texts (homiletic, historical, hagiographic, and poetic) relating to the Monastery and its history from the 12th to the 15th century, the Byzantine officials associated with it, and the celebration of the principal festivals in its churches. It also contains critical editions of and commentaries on the two versions of the Synaxarion of Irene Komnene, a speech referring to the Empress¿s associate in the construction of the Monastery, another on the translation of the icon of St. Demetrios from the Church of St. Demetrios in Thessalonica to the Monastery of Pantokrator, an Office of the Translation of the Holy Stone, the verse Synaxarion composed for the consecration of the Monastery, and the known and unpublished poems by Byzantine poets (12th-15th c.) relating to it, as well as an extensive bibliography.
