Although Trebizond was rebuilt after being pillaged by the Goths in 258, the city did not soon recover.
Only in the reign of Diocletian appears an inscription alluding to the restoration of the city; Ammianus Marcellinus could only write of Trebizond that it was "not an obscure town." Christianity had reached Trebizond by the third century, for during the reign of Diocletian occurred the martyrdom of Eugenius and his associates Candidius, Valerian, and Aquila.
During the early modern period, Trabzon, because of the importance of its port, again became a focal point of trade to Persia and the Caucasus. (τράπεζα meant "table" in Ancient Greek; note the table on the coin in the figure.) Both in Pontic Greek and Modern Greek, it is called Τραπεζούντα (Trapezounta).
In Ottoman Turkish and Persian, it is written as طربزون. in Georgian it is ტრაპიზონი (T'rap'izoni) and in Armenian it is Տրապիզոն Trapizon.
When the kingdom was annexed to the Roman province of Galatia in 64–65, the fleet passed to new commanders, becoming the Classis Pontica.
