Fulvius Sparsus
We do not know his origins, although he may be Spanish as there are Spanish inscriptions referring to the Fulvii Sparsi. He studied under Porcius Latro. Seneca described him as “hominem inter scholasticos sanum, inter sanos. scholasticum” (Cont 1.7.15). Seneca cites him c. 25 times in the extant material, and judging by these, he was fond of opposition and antithesis, sometimes leading to affectedness in his style: this citation is a good example of that.
