What is "philanthropenos"

Philanthropenos , feminine form Philanthropene , was the name of a noble Byzantine Greek family which appeared in the mid-13th century and produced a number of high-ranking generals and officials until the end of the Byzantine Empire. Their name derives from the monastery of Christ Philanthropos ("Christ Friend of Man") in Constantinople. Some members of the family use the composite surname Doukas Philanthropenos, and may, according to Demetrios I. Polemis, constitute a distinct branch of the family.
