Piso (general under Macrianus)

Lucius Calpurnius Piso Frugi (fl. 261 AD) was probably a Roman general whom the imperial pretender Macrianus Major sent to suppress the governor of Achaia, Valens Thessalonicus. His existence is attested only by the unreliable Historia Augusta, which labels Piso as one of several usurpers who plagued the reign of Emperor Gallienus. While some historians grudgingly regard Piso as a historical figure, many reported details of his life, including his usurpation, are dismissed as fabrications.^[1][2][3]
