Marcus Pontius Laelianus Larcius Sabinus was a Roman senator and general who held a series of offices in the emperor's service.
According to Anthony Birley, the origin of Laelianus is indicated by his tribe, Pupina, whose members are found only in Italy "with the single exception of Baeterrae in Narbonensis, where he served twice."
[3] Edmund Groag suggested that Laelianus married Pompeia Sosia Falconilla, the daughter of Quintus Pompeius Sosius Priscus, consul ordinarius in 149.
Professor William McDermott supports this suggestion: "The gap in ages is wide, but not much more than that of Pliny and his third wife Calpurnia.
[7] Once he completed his service with this unit, he served as quaestor for Gallia Narbonensis; he was the emperor's candidate for plebeian tribune, and held the third and last of the Republican magistracies, praetor.
Next he was a member of the sodales Antoniniani, the priests in charge of the cult of Antoninus Pius; this membership he likely resigned from when he was admitted to the College of Pontiffs.
