The Annals and the Histories · Ann. 4.65

It will not be uninteresting to mention that Mount Caelius was anciently known by the name of Querquetulanus, because it grew oak timber in abundance and was afterwards called Caelius by Caeles Vibenna, who led the Etruscan people to the aid of Rome and had the place given him as a possession by Tarquinius Priscus or by some other of the kings. As to that point historians differ; as to the rest, it is beyond a question that Vibenna's numerous forces established themselves in the plain beneath and in the neighbourhood of the forum, and that the Tuscan street was named after these strangers.
