Strabo Geography 7.5.7

[7] Be this as it may, after the seaboard of the Ardiaei and the Pleraei come the Rhisonic Gulf, and the city Rhizo, ¹ and other small towns and also the River Drilo, ² which is navigable inland towards the east as far as the Dardanian country. This country borders on the Macedonian and the Paeonian tribes on the south, as do also the Autariatae and the Dassaretii—different peoples on different sides being contiguous to one another and to the Autariatae. ³ To the Dardaniatae belong also the Galabrii, ⁴ among whom is an ancient city, ⁵ and the Thunatae, whose country joins that of the Medi, ⁶ a Thracian tribe on the east. The Dardanians are so utterly wild that they dig caves beneath their dung-hills and live there, but still they care for music, always making use of musical instruments, both flutes and stringed instruments. However, these people live in the interior, and I shall mention them again later.

[7] After the termination of the coast of the Ardiaei and Pleraei is the bay of the Rhizaei, a city Rhizon, ¹ other small towns, and the river Drilon, ² which may be navigated up its stream towards the east as far as Dardanica. This country is situated close to the Macedonian and Paeonian nations, towards the south, as also the Autariatae and the Dasaretii are in parts contiguous to one another [and to the Autariatae]. ³ To the Dardaniatae belong the Galabrii, ⁴ in whose territory is an ancient city; and the Thunatae, who approach on the east close to the Maedi, ⁵ a Thracian tribe.

The Dardanii are entirely a savage people, so much so that they dig caves beneath dungheaps, in which they dwell; yet they are fond of music, and are much occupied in playing upon pipes and on stringed instruments. They inhabit the inland parts of the country, and we shall mention them again in another place.
