The Diocese of Termia or Diocese of Thermae or Diocese of Thermia (Latin: Dioecesis Thermiensis seu Firminiensis) was a Latin Catholic crusader bishopric located in the
Cycladesarchipelago in the
Aegean Sea.[1][2] It was originally established as the Diocese of Ceo in 1330, before being renamed in 1600. The
diocese was reestablished as a
titular see in 1933 under the name Titular Episcopal See of Cea.
History
The diocese in the
Cyclades was first established in 1330 as the Diocese of Ceo, part of the Venetian
Duchy of Naxos, on the island of
Kea.[2] In 1600, the
bishopric was moved from Kea to
Kythnos, and the diocese was renamed the Diocese of Thermia.
Ordinaries of the diocese observed
Roman Rite.[2]
In 1650, the Cyclades were conquered by the
Ottoman Empire and the diocese's activities were suppressed. The diocese was nominally restored as the Titular Episcopal See of Cea in 1933,[2] and remains listed as such today.[3]
Since the diocese's nominal restoration in 1933, under the name Cea, it has had the following incumbents, so far of the fitting Episcopal (lowest) rank, but is vacant since decades:[2]
