(Mark 6:27). Instead of the Greek word, Mark here uses a Latin
word, speculator, which literally means "a scout," "a spy," and
at length came to denote one of the armed bodyguard of the
emperor. Herod Antipas, in imitation of the emperor, had in
attendance on him a company of speculatores. They were sometimes
employed as executioners, but this was a mere accident of their
office. (See MARK, GOSPEL OF T0002421.)
