[8] Details of Celer's life are lacking before 20 May 75, when he first appears in the records of the Arval Brethren as a member of that college.
[10] He returned to Rome to serve as suffect consul in 77, and attended all the known ceremonies of the Arval Brethren until 86, and does not appear again until 27 May 90.
Syme explains his absence by dating Celer's term as juridicus of Tarraconensis to these years.
[12] In AD 91, when he was eligible to participate in the sortition for the proconsulate of either Africa or Asia, he failed to obtain either one.
[13] Some authorities raise the possibility that Pompeia Celerina, the mother of Pliny the Younger's second wife, was Celer's daughter.
