Gaius Blossius was, according to Plutarch, a philosopher and student of the Stoic philosopher Antipater of Tarsus, from the city of Cumae in Campania, Italy, who instigated Roman tribune Tiberius Gracchus to pursue a land reform movement on behalf of the plebs. Tiberius was accused by his political opponents of attempting to provoke a popular uprising, and have himself crowned King. Eventually, he was assassinated, and his body thrown into the river Tiber.
