Titular see, suffragan of Cyrene, in the Libya Pentapolis. Under this name it is not found in any "Notitia episcopatuum", nor in any geography sacred or profane. Nevertheless, at the Robber Synod of Ephesus (449), we find a Theodulus, Bishop of Ticelia in Libya (Mansi, "Conciliorum Collectio", VI, 610); the name of the city is much corrupted in the Greek text. It is doubtful if Ticelia is the correct name of this city or see. In a "Notitia episcopatuum", published by Gelzer (Byzantinische Zeitschrift, II, 26), we find the see of Sicelia, evidently the same as ours. Which is the correct name? At the Council of Ephesus (431), among the subscribers is Sosipater, Bishop of Septimiace, a city otherwise unknown, which seems likewise to have been situated in Libya (Mansi, op. cit., IV, 1128, 1221). Just now it is impossible to say if these various names relate to the same city, or what is the correct name of the diocese.
