Antecessōres
called also Antecursōres. Roman horse-soldiers, who were accustomed to precede an army on march in order to choose a suitable place for the camp, and to make the necessary provisions for the army. They do not appear to have been merely scouts, like the speculatores. This name was also given to the teachers of the Roman law. (Cod. Iust. i. 17, 2.)
