He had drawn up (about 550) a purely canonical compilation in 50 titles, and later composed an extract from the Justinian's Novellae in 87 chapters[1] that relate the ecclesiastical matters.
[2] The second nomocanon dates from the reign of the Byzantine Emperor Heraclius (610–641), at which time Latin was replaced by Greek as the official language of the imperial laws.
The great systematic compiler of the Eastern Church, who occupies a similar position to that of Gratian in the West, was Photius, Patriarch of Constantinople in the 9th century.
The Nomocanon of Photios supplemented the Pedalion (Greek: Πηδάλιον 'rudder'), a sort of Corpus Juris of the Eastern Orthodox Church, printed in 1800 by Patriarch Neophytos VII.
The Nomocanon of Photios retained in the law of the Eastern Orthodox Church and it was included in the Syntagma, published by Rallis and Potlis (Athens, 1852–1859).
In order to overcome this problem and organize legal system, after acquiring religious independence, Saint Sava finished his Zakonopravilo in 1219.
During the Serbian Revolution, in 1804 the priest Mateja Nenadović established the Nomocanon of Saint Sava as the code of the liberated Serbia.
