This was the least desirable office to hold, for men who held it rarely had a successful career: Anthony Birley could find only five tresviri capitales who went on to be governors of consular imperial provinces.

According to Mireille Corbier, this was part of an effort by the emperor Hadrian to regularize the finances of cities in the Roman Empire; the senator Publius Pactumeius Clemens carried out similar duties at the same time.
Ligarianus' first consular office was curator operarum locorumque publicorum, or overseer of the public works and places of Rome, around 136; his immediate successor was Papus, who is attested in that position 15 May and 13 December 138.
[8] Ligarianus succeeded the historian Arrian as governor of Cappadocia, an office he held at the time of Hadrian's death (10 July 138); which years his tenure began and ended are uncertain.
