CALCULA´TOR
CALCULA´TOR (
λογιστής) signifies a keeper of accounts in general, but was also
used in the signification of a teacher of arithmetic (Isid.
Orig. 1.3;
Dig. 38, tit. 1, s. 7);
whence Martial (
10.62,
4) classes him with the
notarius or
writing-master ; but the teacher of arithmetic held a high position among
teachers (cf. Cod.
Just. 10, tit. 52, s. 4;
Becker-Göll,
Gallus, ii. p. 101;
Marquardt,
Röm. Privatleben, p. 95). The name was
derived from
calculi, which were commonly used
in teaching arithmetic, and also in reckoning in general. [
ABACUS] Among the Greeks the
λογιστὴς and
γραμματιστὴς appear to have been usually the same person.
