Magydus was a small town with no notable history, on the coast between Attaleia and Perga, mentioned occasionally by geographers of the Roman and Late Antiquity periods,and on numerous coins of the imperial era.
It was nominally restored no later than the late 18th century as Latin Titular bishopric of Magyddus (Latin until 1925, then renamed Magydus) / Magido (Curiate Italian) / Magyden(sis) (Latin adjective).
It is vacant since decades, having had the following incumbents, so far of the fitting Episcopal (lowest) rank :
