Commentary

Cn. Fulvius (RE 12) held the praetorship in 190 BC (Livy 36.45.9, 37.2.1, 37.2.6; Broughton, MRR I) but never advanced to the consulship. His family, however, is a textbook illustration of how remarriage knit together Roman aristocratic gentes in the middle Republic.

His father, Cn. Fulvius (54) Flaccus (pr. 212 BC), was one of three sons of M. Fulvius (55) Flaccus (cos. 264 BC), the first consul of the First Punic War. The elder brother, Q. Fulvius (59) Flaccus, reached the consulship in 237 BC. Through his mother Hostilia Quarta’s second marriage to C. Calpurnius (62) Piso (cos. 180 BC), our subject gained three half-brothers who all attained the consulship: L. Calpurnius Piso Caesoninus (cos. 148), Cn. Calpurnius Piso (cos. 139), and Q. Calpurnius Piso (cos. 135). His full brother Q. Fulvius (60) Flaccus also reached the consulship as consul suffectus in 180 BC.

The praetorial line continued: Cn. Fulvius (12)’s son, Cn. Fulvius (13), held the praetorship in 167 BC. Three successive generations of Cn. Fulvii who reached the praetorship but not the consulship — a respectable but distinctly second-tier trajectory, thoroughly overshadowed by siblings on every side.
