Plinius den eldre: Naturalis Historia, 4.26. «Leaving Taphræ, and going along the mainland, we find in the interior the Auchetæ, in whose country the Hypanis has its rise, as also the Neurœ, in whose district the Borysthenes has its source, the Geloni, the Thyssagetæ, the Budini, the Basilidæ, and the Agathyrsi with their azure-coloured hair.»
Strabon: Geography, 7.6.1. «On this coast-line is Cape Tirizis, a stronghold, which Lysimachus once used as a treasury.»
Cassius Dio. Roman History, 55.22.6-55.22.7. «The Suebi, to be exact, dwell beyond the Rhine (though many people elsewhere claim their name), and the Dacians on both sides of the Ister; those of the latter, however, who live on this side of the river near the country of the Triballi are reckoned in with the district of Moesia and are called Moesians, except by those living in the immediate neighbourhood, while those on the other side are called Dacians and are either a branch of the Getae are Thracians belonging to the Dacian race that once inhabited Rhodope.»
Arrian: Anabasis, Bok IA. «The Getae did not sustain even the first charge of the cavalry; for Alexander’s audacity seemed incredible to them, in having thus easily crossed the Ister, the largest of rivers, in a single night, without throwing a bridge over the stream. Terrible to them also was the closely locked order of the phalanx, and violent the charge of the cavalry. At first they fled for refuge into their city, which. was distant about a parasang from the Ister; but when they saw that Alexander was leading his phalanx carefully along the side of the river, to prevent his infantry being anywhere surrounded by the Getae lying in ambush, but that he was sending his cavalry straight on, they again abandoned the city, because it was badly fortified.»
