Sling: the ancient means for hurling missiles against the enemy(called also a swepe) occurs in one or two coats of arms, though not in any ancient ones, so far as has been observed. The sling, or staff-sling, is represented as in the margin.
The sweep(more correctly spelt swepe) is used as if synonymous. It is, however, the same as the balista, and is so blazoned in one coat; it is a more formidable engine of warfare, similar to the catapult or mangonel, whence in one case the play on the name.
