entitled to his freedom, because his master had voluntarily treated him
as free."

Formerly, they called these by a Greek term, syntaxeis, but of late
"controversies;" but they may be either fictitious cases, or those which
come under trial in the courts. Of the eminent professors of this
science, of whom any memorials are extant, it would not be easy to find
many others than those of whom I shall now proceed to give an account.

II. LUCIUS PLOTIUS GALLUS. Of him Marcus Tullius Cicero thus writes to
Marcus Titinnius [908]: "I remember well that when we were boys, one
