bacillum

1. Fustis and ferula denote sticks for striking; sudes, trudes, and rudis, for thrusting; scipio and baculus, for walking. 2. Fustus (πτορθός?) is a cudgel or club, large enough to strike a man dead; but ferula, a little stick, or rod for the chastisement of school-boys; sudes (ὄζος) and trudes (στορθή, the root of Trüssel, a weapon called the Morning-star) [a sort of truncheon with a spiked head], are used in battle; rudis (ὀρσός) only as a foil in the fencing-school; scipio (σκηπίων, σκῆψαι), serves especially for ornament and state, as a symbol of superior power, or of the honor due to age; baculus, bacillum (βάκτρον), serve more for use and convenience to lean upon, and at the same time, when necessary, as a weapon. (iii. 265.)
