What is "tyragetae"

The Tyrageti, Tyragetae, or Tyrangitae (, Strabo vii.; Ptol. iii. 5. § 25), literally, the Getae of the Tyras, were a sub-tribe of the Getae Thracians, situated on the river Tyras (modern day Dniester in Moldova and Ukraine). They were regarded as an immigrant tribe of European Sarmatia dwelling E. of the river Tyras, near the Harpii and Tagri, and, according to Ptolemy, the northern neighbours of Lower Moesia. Pliny (v. 12. s. 26) calls them, with more correct orthography, Tyragetae, and represents them as dwelling on a large island in the Tyras.
