Arathia

Arathia was a city and bishopric in the late Roman province of Cappadocia Prima, Asia Minor, whose ecclesiastical metropolis was at Caesarea (modern Kayseri, Turkey). Its location is unknown. The bishopric was revived as Latin Catholic titular see in the 18th century.
History.
The ancient city was important enough to become a bishopric in the late Roman province of Cappadocia Prima (civil Diocese of Pontus), in the sway of the Patriarchate of Constantinople, but would fade completely, plausibly at the advent of Islam. Neither its precise location is known, nor any residential bishop.
Titular see.
The diocese was nominally restored as Latin Catholic titular bishopric no later than 1755 under the names Arathia / Arata (Curiate Italian) / Arath / Aratia (Latin) / Arathen(sis) / Arathien(sis) (Latin adjective).
It has been vacant since 1853 (effectively suppressed?), having had the following incumbents, all of the fitting Episcopal (lowest) rank :
