Metropolis of Larissa and Tyrnavos

[4] Some time between 730 and 751, the Church in Thessaly, along with the rest of the Illyricum, were transferred from the jurisdiction of the Pope in Rome to that of the Patriarch of Constantinople.

[6] In the middle Byzantine period, the Notitiae Episcopatuum show Larissa with ten suffragan sees; these were in order Demetrias, Pharsalus, Thaumakos, Zetouni (Lamia), Ezeros, Loidoriki, Trikke, Echinus, Kolydros, and Stagoi.

[9] Subsequently, the number of suffragans increased and about the year 1175 under the Emperor Manuel I Comnenus, it reached twenty-eight.

[10] Following the Fourth Crusade and Thessaly's incorporation into the Kingdom of Thessalonica, a Roman Catholic archbishop was installed in the place of the previous Greek Orthodox metropolitan.

[12] At the close of the 15th century, under the Turkish domination, there were only ten suffragan sees,[13] which gradually grew less and finally disappeared.
