Strabo Geography 4.6.8

[8] Beyond, both the eastern parts of the mountains, and those likewise inclining to the south, are possessed by the Rhaeti and Vindelici, who adjoin the Helvetii and Boii, and press upon their plains. The Rhaeti extend as far as Italy above Verona and Como. The Rhaetian wine, which is esteemed not inferior to the finest wines of Italy, is produced [from vines which grow] at the foot of the mountains. These people extend also as far as the districts through which the Rhine flows. The Lepontii and Camuni are of their nation. The Vindelici and Norici possess, for the most part, the opposite side of the mountains together with the Breuni and Genauni, who form part of the Illyrians. ¹ All these people were continually making incursions both into the neighbouring parts of Italy, and into [the countries] of the Helvetii, the Sequani, ² the Boii, and the Germans. ³ But the Licattii, the Clautinatii, and the Vennones ⁴ proved the boldest amongst the Vindelici; and the Rucantii and Cotuantii amongst the Rhaeti. Both the Estiones and Brigantii belong to the Vindelici; their cities are Brigantium, Campodunum, and Damasia, which may be looked upon as the Acropolis of the Licattii. It is narrated, as an instance of the extreme brutality of these robbers towards the people of Italy, that when they have taken any village or city, they not only put to death all the men capable of bearing arms, but likewise all the male children, and do not even stop here, but murder every pregnant woman who, their diviners say, will bring forth a male infant. ⁵
