warehouses for the salt that was brought up the Tiber in boats
and carried inland by the via Salaria-probably the earliest kind of
traffic between Rome and the sea coast. They were situated on and
adjacent to the site of the porta Trigemina (Solin. i. 8
; Frontinus, i. 5;
Liv. xxiv. 47
. 15), probably outside this gate after it was built (cf. Plaut.
Capt. go; BC 1888, 84-91
pass.; RE i. A. 2078).
