7 Cicero lists Metellus between two Tribunes who held office in 90 in a group of magistrates then in office (Brut. 305; and note the phrase consequente anno referring to 89 B. C.). (Broughton MRR II)
5 Seidel (FA 48) identifies the Aedile with this Metellus rather than his son the Consul of 60, though the Sergius Silus who is mentioned (RE no. 9, cf. 38; Cic. Verr. 2.3.102) would point to the latter if he were the one involved. If the tribunate of the Consul of 60 is correctly attributed to 68, he must have held the aedileship in 67 or else not at all, for he was a Legate under Pompey in 66. (Broughton MRR II)
He tried and condemned, probably as Aedile (Mommsen, Str. 2.493, note 4), Cn. Sergius Silus (RE no. 38) for improper proposals to a matron (Val. Max. 6.1.8). (Broughton MRR II)
Aed.? 88? It is uncertain to whom the aedileship of a Metellus Celer (Val. Max. 6.1.8) should be attributed (see MRR 2.41, 45, note 5, 144- and 539), but since the future consul of 60 (86) was very probably a tribune of the plebs in 68, and legatus of Pompey in 67, the earlier Metellus Celer is a better candidate (Sumner, Orators 132-133).
