Jordanes introduces us to the Turcilingi, though he makes no mention of them at Châlons. The Turcilingi were joined with several other barbarian tribes, like the Sciri, Rugii, and Heruli, under Odovacar as foederati of the Western Roman Emperor Romulus Augustulus, who was a puppet of his father, Flavius Orestes. The barbarians demanded from Orestes in return for their military service some Italian land on which to settle. They were denied. According to Jordanes:
Now when Augustulus had been appointed Emperor by his father Orestes in Ravenna, it was not kong before Odoacer, king of the Torcilingi (rex Torcilingorum), invaded Italy, as leader of the Sciri, the Heruli and allies of various races. He put Orestes to death . . . (XLVI.242)When Theodoric the Great was looking for a pretext to invade Italy in 493, he petitioned the Eastern Roman Emperor Zeno by reminding him of the "tyranny" (unlawful rule) of the city of Rome by Turcilingi and Rugii. According to Jordanes, Theodoric gave the following justification:
The western country, long ago governed by the rule of your ancestors and predecessors, and that city which was the head and mistress of the world—wherefore is it now shaken by the tyranny of the Torcilingi and the Rugi (sub regis Thorcilingorum Rogorumque tyrannide)? (LVII.291)Theodoric's charge against the Turcilingi had resonance. As late as the seventeenth century, Lancelot Andrewes found use for citing the "inhumanity" and barbarity of the Turcilingi in his Gunpowder Plot Sermon.
Paul the Deacon, in his opening chapter (I.1), names several peoples (Vandals, Rugii, Heruli, Turcilingi) who have come, he says, from Germania to Italy. He goes on to name the Lombards as latecomers from the same region. This passage is clearly based on Jordanes, but its reference to Germany is unique. Nonetheless, Paul does not say that the Turcilingi are Germans: "The Goths indeed, and the Wandals, the Rugii, Heroli, and Turcilingi, and also other fierce and barbarous nations have come from Germany." The Turcilingi appear to have originated in Germany, perhaps near the Baltic Sea, and thence moved with the Huns into Gaul and finally to the Danube, possibly Noricum, before entering Italy with Odovacar.
Nineteenth-century German scholarship supposed that the Turcilingi were neighbours of (or the same people as) the Sciri in the first century, or that they were the royal clan of the Sciri or the Huns. The more enthusiastic invented a homeland for them straddling the Oder, with the Sciri to the east, the Vandals to the west, and the Rugii to the north. These scholars placed them in the Gothic mouvance.
Completely Turkic etymologies for the name "Turcilingi" have been proposed. Türk-lük or "Turkdom" is a plausible starting point, suggested by Edouard Blochet. The Turkic given names Ṭoghril, Ṭoghrul, or Ṭogrul could form the basis of a Germanicised tribal name. The Pecheneg name Turak is an alternative suggestion. The Gothic form *Taurkiliggos has been hypothesised as a root meaning "descendants of the *Taurkeis", that is, Turks.
Based on his Turkic name, Aspar may have been Turcilingian.
