last date depends, extend from September 99 to July 100 A.D.
(_Philologus_, xxx. 347 _sqq._).

_Paneg._ 92, 'Nobis praefectis aerarii consulatum ante quam
successorem dedisti.'

Pliny, along with Cornutus Tertullus, his colleague in the
_praefectura_, was made consul A.D. 100. He held the office in
September of that year, and the tenure was either from July 1 to
September 30, or from September 1 to October 31.

_Paneg._ 92, 'Ei nos potissimum mensi attribuisti quem tuus natalis
exornat.'

The _Panegyricus_ is a speech of thanks to Trajan spoken on this
occasion. In A.D. 99 Pliny, along with Tacitus, appeared for the
Africans against the proconsul Marius Priscus (see _Ep._ ii. 11 quoted
p. 338); and in A.D. 101, while still _praefectus aerarii_, he
appeared for the people of Baetica against the proconsul Caecilius
Classicus.

_Ep._ iii. 4, 2, 'Legati provinciae Baeticae questuri de proconsulatu
Caecili Classici advocatum me a senatu petierunt.'

Pliny obtained the augurship, probably in 103 or 104, in succession to
Sex. Iulius Frontinus, who probably died in 102 or 103 A.D. Cf. _Ep._
iv. 8, 3, 'Successi Iulio Frontino.' In 103 or 104 A.D. he appeared
against the Bithynians for the proconsul Iulius Bassus (_Ep._ iv. 9
etc.). He held the _cura alvei Tiberis et riparum et cloacarum urbis_
probably from 105 to 107 A.D. See Pliny's chief inscription (below),
and cf. _Ep._ v. 14, 1-2, 'Mihi nuntiatum est Cornutum Tertullum
accepisse Aemiliae viae curam ... aliquanto magis me delectat mandatum
mihi officium, postquam par Cornuto datum video.'

About A.D. 106 Pliny appeared against the Bithynians for the proconsul
Varenus Rufus (_Ep._ vi. 29, 11).

From 111-2 or 112-3 A.D. Pliny was governor of Pontus and Bithynia,
being sent out for a special purpose by the emperor as _legatus pro
praetore consulari potestate_. Cf. the chief inscription (below) and
the words of Trajan.

_Trai._ 32, 'Meminerimus idcirco te in istam provinciam missum, quoniam
multa in ea emendanda apparuerint.'

The date of Pliny's governorship is fixed by the mention of Calpurnius
Macer in the letters (_ad Trai._ 42; 61; 62) as the governor of the
nearest province. Mommsen has identified him with P. Calpurnius Macer
Caulius Rufus, who is shown by an inscription (_C.I.L._ iii. 7 and 17)
to have been governor of Lower Moesia in 112 A.D. This is corroborated
by the fact that no mention is made of Bithynia in the chief
collection of letters, which was
