Tavium

 ( Roman Towns And Cities In Turkey ) 

Tavium, or Tavia (; ), was the chief city of the tribe of Trocmi, one of the three tribes which migrated from the Danube Valley to Galatia in present-day central Turkey in the 3rd century BCE. Owing to its position on the high roads of commerce, Tavium was an important trading post. The site was successively occupied by Hittites, Cimmerians, , Celts, Greeks, Romans, Seljuk Turks and Ottoman Turks. At the time of the Roman Empire, Tavium was an important crossroads and a stopping place on the caravan routes.

One of the few things known about Tavium is that there was metalworking; this is known from coins minted there in the early 1st century that bear the likenesses of Marcus Aurelius and Elagabalus. Copper, tin, iron and silver were mined in the nearby mountains. Similar to other Celtic towns of the time, the smelting and stamping was done by a small group of artisans working in one or two stone huts. In the city there was a colossal bronze statue of Zeus, Strabo, Geography, §12.5.2 who was greatly venerated by the Galatians.

The site of Tavium is generally believed to be ruins situated close to the village of Büyüknefes (previously known as Nefezköy), in a fertile plain east of the Kızılırmak river (ancient Halys) in Yozgat Province. Materials from these ruins were used in building the neighbouring town of Yozgat, which also features the remains of a theatre and, possibly, a temple of Jupiter; these have a number of inscriptions, mostly Byzantine Empire.

Archaeological surveys have been conducted at the site by Karl Strobel and Christoph Gerber since 1997. Strobel, K.; Gerber, C. (2010). “Tavium (Büyüknefes, Provinz Yozgat) und seine Region Bericht über die Kampagnen 2006–2009.” Istanbuler Mitteilungen 60: 291-338.

In the Notitiæ Episcopatuum the bishopric of Tavium is mentioned up to the 13th century as the first suffragan of Ankara. The names of five bishops of the area are known: Dicasius, present at the Councils of Niksar and Nice; Julian, at the second Council of Ephesus (449), and at the Council of Chalcedon (451), and a signer of the letter from the Galatian bishops to the Emperor Leo (458); Anastasius, present at the second Council of Constantinople (553); Gregory at the Council in Trullo (692); Philaretus at Constantinople (869).

As of the early 20th century, Büyüknefes was inhabited during the winter by nomadic Turkish tribes. It was then in the kaza (district) of Sungurlu and the vilayet of Ankara. Now it is a part of Yozgat Province.
