The dating of Pliny's latest letters

When announcing the first instalment, the author made a firm declaration: ‘collegi non servato temporis ordine’. The note of elegant disdain suitably echoes a poet: ‘postmodo collectas, utcumque sine ordine iunctas’;. In fact, care for balance and variety predominates. Nevertheless, when Pliny came to recount public transactions, he had to respect a ‘temporis ordo’, as many signs indicate. Mommsen in his classic study was able to work out the chronological framework, of the nine books, from 97 to 108 or 109. In general, his scheme stands the test — that is, apart from the notion of a rapid publication in separate books. Indeed, no argument avails to prove that the first instalment saw the light of day earlier than the end of the year 105. Pliny was expert in finance and an alert contriver everywhere. Persons of that quality may succumb to inadvertence, although not very often. Licinius Nepos, praetor in 105, comes twice into action (4.29; 5.4), before his edict gets a mention (5.9). Again, in a letter the context of which points to 105, a consulship for Minicius Fundanus is divined ‘in proximum annum’ (4.15.5). Fundanus entered office in the early summer of 107. By contrast, Valerius Paulinus, consul suffect in the pair that followed that consulship, does not come up until 9.37. An extremely late point in the collection. It imposes a salutary warning when a number of letters in the final triad are put under scrutiny. The exposition of Mommsen ran into criticism, sometimes hasty or even perverse. Moreover, various attempts were made to modify the dates of certain prosecutions in the Senate. The emergence of a consul on the Fasti Ostienses demolished an elaborate reconstruction that concerned two proconsuls of Bithynia. More accruing, a number of fairly close dates can now be established.
