Ulpian’s life table is an ancient Roman annuities table. It is known through a passage, originating from the jurist Aemilius Macer, preserved in edited form in Justinian’s Digest. The table appears to provide a rough outline of ancient Roman life expectancy. Although it is not clear what population the table refers to, or how its data was gathered, Richard Duncan-Jones has suggested that it refers to slaves and ex-slaves, who were often the object of testamentary maintenance grants.
Aemilius Macer probably lived in the 230s AD. He records the table in his systematic commentary on the lex Julia de vicesima hereditatium, an Augustan law of 6 AD that put a 5 percent tax on inheritances. Despite its many numbers, the fragment does not appear to be afflicted by any serious textual corruption.
