[1] Balsamon's best work is his "Scholia" (Greek: Σχόλια) (c. 1170), a commentary on the Nomocanon of Photios, the standard work on Eastern Orthodox ecclesiastical and imperial laws and decrees, commissioned by the Emperor Manuel I and the Patriarch Michael III.
Balsamon also compiled a collection of ecclesiastical constitutions (Syntagma) and wrote other works, many of which concern the ongoing debate between the Eastern and Western Churches following the schism of 1054.
[1] Theodore's legacy is that he preserved the world's knowledge of many otherwise unknown source documents from early Byzantine political and theological history.
His commentaries are still referenced to this day by students of Eastern Orthodox canon law.
From 1852 to 1860, Rhalli and Potli published at Athens a collection of the sources of Greek canon law which contains Balsamon's commentary.
