Based on lunar dates which are known to belong to the reign of his rival Takelot II in Upper Egypt and the fact that Pedubast I first appeared as a local king at Thebes around Year 11 of Takelot II's rule, Pedubast I is today believed to have had his accession date in either 835 BC or 824 BC.

[3] Pedubast I was the main opponent to Takelot II and later, Osorkon B, of the 23rd Dynasty of Libyan kings of Upper Egypt at Thebes.

The richly inlaid torso from a bronze statue that originally depicted Pedubast I is today on permanent display in the Calouste Gulbenkian Museum in Lisbon, Portugal and is considered to be one of the great masterpieces of Egyptian Third Intermediate Period Art.

[4] This object was purchased by Calouste Gulbenkian from December 13–16, 1921 from Frederik Muller & Cie through the well-known art dealer Joseph Duveen.

"[7] This object's provenance is not known but it is first recorded as being in the collection of Count Grigory Stroganoff (1829–1910), a member of the famous Russian family of connoisseurs and collectors, in 1880.
