The full title of the town was Colonia Iulia Augusta Prima Fida Comama. The first term in this title indicates that it was founded as a colonia, an outpost established in conquered territory to secure it. The presence of the term Augusta indicates that it was founded after 27 BC, when the Roman senate granted that title to the victorious Octavian. Comama was one of a group of such settlements established in the area, which were linked by an imperial road called the Via Sebaste, one milestone of which (XLV) has been found at Comama. The milestones were set up in about 6 BC, an indication of the date of foundation of Comama.
The site was at Şerefönü in present-day Turkey.
