[2] The earliest office recorded on this inscription was quattuorviri viarum curandarum, one of the four boards that comprised the vigintiviri; membership in one of these was a required first step toward a gaining entry into the Roman Senate.
His next recorded office was as quaestor of the senatorial province of Achaea; upon completion of this traditional Republican magistracy he would be enrolled in the Senate.
[3] The inscription omits all mention of a term of service as military tribune; John D. Grainger speculates that Senecio may have served with Legio XXI Rapax, which was destroyed by the Iazyges in 92.
[7] The second is a request for a commission as military tribune on behalf of a relative of Pliny's friend Gaius Calvisius Rufus.
[8] Plutarch also dedicated several of his Parallel Lives (Theseus 1, Demosthenes 1, Brutus 1) as well some of the individual Moralia (Quaestiones conviviales and Quomodo quis suos in virtute sentiat profectus) to Senecio.
