Calo
A common slave; often the slave of a soldier. The word is a contraction of
caclo, akin to
cacula. (See Fest. p. 146.) Even under
the Republic the number of slaves following a Roman army was large; under the Empire it
sometimes exceeded the number of the soldiers. Each legion was followed by its own
calones; and to prevent confusion, in case of an attack, they were organized
and subjected to military discipline. See Lixa;
Servus.
