Theodelap or Theudelapius^[1] was one of the sons of Faroald, the first Duke of Spoleto.^{[2][self-published source?]} After the death of Ariulf in 601 or 602, Theodelap and his brother fought for the throne. Theodelap won and was crowned duke. He held the dukedom for more than half a century, until his death.^[3] His reign was nevertheless uneventful and he appears to have been largely or completely independent of royal authority throughout. He was succeeded by Atto.
