The gens Sepullia was a minor plebeian family at ancient Rome.
Hardly any members of this gens are mentioned in ancient writers, of whom the most famous was Sepullius Bassus, a rhetorician known to Seneca the Elder.
[2] The nomen Sepullius belongs to a class of gentilicia apparently formed from cognomina ending in the diminutive suffix -ulus.
[3] In this case, the nomen would have derived from Sepulus or a similar name, presumably a diminutive of the old Latin praenomen Septimus, originally given to a seventh son or seventh child, or Seppius, its Oscan equivalent.
[4] The Sepullii were perhaps from Patavium in Venetia and Histria, as several of the inscriptions bearing this name are from that area.
