perhaps you'd prefer to read it in the original language:

Genus spectaculorum unum atque in omni coetu idem. Nudi iuvenes, quibus id ludicrum est, inter gladios se atque infestas frameas
saltu iaciunt.

So, it's true (except that some parts of the text may have been written later than 98 which is usually taken as the date of his 'De origine et situ Germanorum')
