Theophilus Protospatharius (Greek: Θεόφιλος Πρωτοσπαθάριος; ca.
He is generally called "Protospatharius", which seems to have been originally a military title given to the colonel of the bodyguards of the emperor of Constantinople (Spatharioi); but which afterwards became also a high court title, or was associated with the government of provinces and the functions of a judge.
It is conjectured that he lived in the 7th century; that he was the tutor to Stephanus Atheniensis; that he arrived at high professional and political rank; and that at last he embraced the monastic life.
All this is, however, quite uncertain; and with respect to his date, it has been supposed that some of the words which he uses belong to a later period than the seventh century; so that he may possibly be the same person who is addressed by the title "Protospatharius " by Photius,[1] in the ninth.
He appears to have embraced in some degree the Peripatetic philosophy; but he was certainly a Christian, and expresses himself on all possible occasions like a man of great piety: in his physiological work especially he everywhere points out with admiration the wisdom, power, and goodness of God as displayed in the formation of the human body.
