Several Thracian graves or tombstones have the name Rufus inscribed on them, meaning "redhead" – a common name given to people with red hair

A fragment by the Greek poet Xenophanes describes the Thracians as blue-eyed and red haired:

...Men make gods in their own image; those of the Ethiopians are black and snub-nosed, those of the Thracians have blue eyes and red hair.
