JACULATO'RES. Javelin men; furnished by the allies to the Roman armies, and so termed from the dart (jaculum), which they used, in contradistinction to the slingers and archers (funditores, sagittarii); though all three were classed amongst the light-armed troops, and were employed in the same service, to commence a battle by annoying the enemy with showers of their missiles. Liv. xxi. 21. xxxvi. 18.

2. Fishermen who use the cast net (jaculum). Plaut. ap. Isidor. Orig. xix. 5. 2.
