Trocmade(s) (or Trocmada) was a city of the Eastern Roman Empire in the province of Galatia Secunda. It appears to have been on the site of the modern Turkish village of Kaymaz, about twenty-four miles east of Eskişehir, Turkey.
The city is known from ecclesiastical records; no geographer or historian mentions a city of this name; Hierocles' Synecemus (698, 1) gives "regio Trocnades", instead of Regetnoknada, referring, doubtless, to the Galatian name of some tribe on the left bank of the Sangarius.
All the Notitiae episcopatuum up to the thirteenth century mention the see Trokmadon among the suffragans of Pessinus; the two most recent (thirteenth century) call it Lotinou; perhaps it should be Plotinou, from St. Plotinus, venerated there. The official lists of the Roman Curia give Trocmadae. Le Quien (Oriens christianus, I, 493), gives Trocmada. From these erroneous forms arises a confusion of the name with the Galatian tribe of Trocmi.
Le Quien gives a list of the known bishops:
Cyriacus, said to have assisted at the First Council of Nicaea (325), is not mentioned in the authentic lists of bishops present at that council.
Trocmades remains a Roman Catholic titular see.
