Note 1775 — BOOK XIV.
Lewis Evans translation
Gradarius is said of a horse "trained to an easy, ambling pace," like that expressed by the word tolutim, cf. ix., Fr. 6 (exactly the contrary to succussator, ii., Fr. 10), xv., Fr. 2. Hence "pugna gradaria," where the advance to the charge is made at a slow pace. So Seneca (Epist., xl.) applies the term to Cicero's style of oratory, "lentè procedens, interpungens, intermittens actionem."
