Frontinus, (40 - 103 A.D.) was a Roman aristocrat and author. His most famous works were on aqueducts (De Aquaeductu), and a military treatise (Stratagemata). Stratagemata discusses military tactics, using examples of Greek and Roman generals. The book was intended to be used by Roman generals, and draws upon Frontinus' experience as a general in Germany under Emperor Domitian.
