[2] Cicero relied on the efforts of Furnius, while tribune, to obtain for him his recall at the end of his first year as proconsul of Cilicia, and, after his return, a supplicatio ("thanksgiving").
[3] A clause, however, which Furnius inserted in his plebiscite, making the recall dependent on the Parthians remaining quiet until the month of August 50 BC, was unsatisfactory to Cicero, since July was the usual season of their greatest activity.
[4] Furnius, as tribune, was opposed to the demands that Julius Caesar should immediately and unconditionally resign his proconsulship of Gaul.
Furnius was one of three officers commissioned by Lucius Antonius to negotiate the surrender of Perusia, and his reception by Augustus was such as to awaken in the Antonians suspicions of his fidelity.
[13] Furnius is probably mentioned by Tacitus, De Oratoribus 21, among the speakers whose meagre and obsolete diction rendered their works impossible to read without an inclination to sleep or smile.
