Greek χαράκωμα ( Lehnw 300). Jastrow and others list a second homonym "bronze" (i.e., from Greek χαλκ...) where the targums render forms of the root נחש, but this may be incorrect. The context there is probably always that of weapons of siege warfare thought to be among the strongest of substances. On the other hand, the apparently related (see Levy) LJLA word כרכמישא clearly means "lead". Page refs. in other dictionaries: DJPA: 270a; Jastrow: 669; Levy Ch-W: 1:387;
