Next to the Chatti, where the channel of the Rhine is well defined and forms a boundary line, live the Usipi and Tencteri. The Tencteri, over and above the general military distinction, excel in the art of horsemanship. Indeed, the fame of the Chatti as infantrymen is no greater than that of the Tencteri as cavalry. This began with their ancestors and their descendants follow suit. The small children ride for sport, the young men compete with one another, even the old men keep at it. Horses are handed down along with the household, the homestead, and the rights of succession. A son inherits them, not necessarily the eldest, as with the rest of the property, but the one who shows himself the fiercest and the best in battle.
