Licinius Calvus q littera non est usus. consultum senati1 ipse scripsit, et ad C. Caesarem senatus consultum. idem optimus maximus scripsit, non ut nos per u litteram.
166 M. FAVONIUS
M. Favonius (praet. 49 BC [questioned by Ryan 1994]; RE Favonius 1) fought alongside M. Iunius Brutus (158) and C. Cassius Longinus at Philippi (42 BC) after the assassination of C. Iulius Caesar (121); captured, he was punished and put to death (Suet. Aug. 13.2; Cass. Dio 47.49.4).
Favonius studied oratory with Apollonius Molo at Rhodes (F 3) and is described as having a direct and impetuous way of speaking, bordering on the offensive (T 1;
T 1 Plut. Brut. 34.4–6
Μάρκος δὲ Φαώνιος, ἐραστὴς γεγονὼς Κάτωνος, οὐ λόγῳ μᾶλλον ἢ φορᾷ τινι καὶ πάθει μανικῷ φιλοσοφῶν, ἐβάδιζεν εἴσω πρὸς αὐτοὺς κωλυόμενος ὑπὸ τῶν οἰκετῶν.  ἀλλ᾿ ἔργον ἦν ἐπιλαβέσθαι Φαωνίου πρὸς ὁτιοῦν ὀρούσαντος· σφοδρὸς γὰρ ἦν ἐν πᾶσι καὶ πρόχειρος. ἐπεὶ τό γε βουλευτὴν εἶναι Ῥωμαίων ἑαυτὸν

Licinius Calvus did not use the letter q. He himself wrote consultum senati [“decree of the Senate”], and to Caesar [C. Iulius Caesar (121)] senatus consultum [“Senate’s decree”; usual form of genitive for this declension]. The same man wrote optimus maximus [“the best, the greatest”], not, as we do, with the letter u [i.e., optumus maxumus; archaic or archaizing form].

Plut. Pomp.60.7; Cic. Att. 4.17.4); he seems to have followed the Cynic school of philosophy (T 1).
Favonius was among senators unhappy with the extensive powers requested for Cn. Pompeius Magnus (111) in autumn 57 BC (Cic. Att. 4.1.7); in early 56 BC Favonius belonged to a group of politicians confronting Cn. Pompeius Magnus (111) (Cic. Q Fr. 2.3.2).
A fragment transmitted for [Favorinus] (52) is sometimes attributed to M. Favonius (see 52).
T 1 Plutarch, Life of Brutus
But Marcus Favonius, who had become a devotee of Cato [M. Porcius Cato (126); cf. Plut. Caes. 21.8] and who engaged with philosophy not so much with reason as with some impetuousness and crazy passion, tried to go in to them [M. Iunius Brutus (158) and C. Cassius Longinus, who had withdrawn to a locked room] and was prevented by their servants.  It was a bit of work, however, to stop Favonius when he rushed toward anything; for he was vehement in all matters and rash. The fact that he was a
