INFRENA'TUS sc. Eques. One who rides without a bridle (frenum), as was the practice of the Numidian horsemen (Liv. xxi. 44.), and some of the northern nations, whose horses were so docile and well broken that they could be managed by voice, without rein or bit, as in the annexed example (Infrenatus/1.1), which represents one of the allied cavalry in the army of Trajan, from the column which bears his name.

2. As a participle of the verb Infreno, it has an exactly contrary signification, meaning bitted and bridled. Liv. xxxvii. 20. Sil. Ital. iv. 314.
