But this devout practice does not seem to have been long continued at the Studion; for we never hear of it in any account of the discipline of the House. The monks of the Studion should therefore not be identified with the Akoimeti who took up such a determined and independent attitude in the theological conflicts under Zeno, Basiliscus, and Justinian the Great.[47] In the course of its history the church underwent noteworthy repairs on two occasions. It was first taken in hand for that purpose, soon after the middle of the eleventh century,[48] by the Emperor Isaac Comnenus (1057-58), who was interested in the House because he and his brother had received part of their education in that 'illustrious and glorious school of virtue.'[49] What the repairs then made exactly involved is unfortunately not stated. But, according to Scylitzes, they were so extensive that 'to tell in detail what the emperor and empress did for the embellishment of the church would surpass the labour of Hercules.'[50] Probably they concerned chiefly the decoration of the edifice. The next repairs on record were made about the year 1290, in the reign of Andronicus II., by his unfortunate brother Constantine Porphyrogenitus. Owing to the neglect of the building during the Latin occupation the roof had fallen in, the cells of the monks had disappeared, and sheep grazed undisturbed on the grass which covered the grounds. Constantine, rich, generous, fond of popularity, did all in his power to restore the former glory of the venerated shrine. The new roof was a remarkable piece of work; large sums were spent upon the proper accommodation of the monks, and the grounds were enclosed within strong walls.[51] Like other monastic institutions, the Studion suffered greatly at the hands of the iconoclast emperors. Under Constantine Copronymus, indeed, the fraternity was scattered to the winds and practically suppressed, so that only twelve old members of the House were able to take advantage of the permission to return to their former home, upon the first restoration of eikons in 787 by the Empress Irene. Under these circumstances a company of monks, with the famous abbot Theodore at their head, were eventually brought from the monastery of Saccudio to repeople the Studion, and with their advent in 799 the great era in the history of the House began, the number of the monks rising to seven hundred, if not one thousand.[52]
