[1] In the 12th century, after a period of decline, it was renovated by the mystikos Nikephoros, who rebuilt it and restored to it its confiscated estates with the financial assistance of Emperor Manuel I Komnenos (r. 1143–1180).
[1] Originally a patriarchal monastery, it now became independent, and in 1162 Nikephoros issued its new regulations (typikon), modelled on those of Theotokos Euergetis and Saint Mamas.
[1] The new regulations limited the number of monks to twenty, both at the monastery itself as well as in its dependency (metochion) in Constantinople.
[1] Heliou Bomon was apparently also known, or at some point united with, a monastery known as "Elegmoi", which is also first mentioned in the 10th century.
[1] The monastery was located in Bithynia, at the modern village of Kurşunlu, and was part of the monastic community of the Bithynian Olympus.
