According to that text, Patigrabana is where Hystaspes – father of Darius I and Achaemenid governor of Parthia – fought a battle against Parthian and Hyrcanian rebels supporting one Phraortes (not to be confused with the earlier Median emperor of the same name) around 520 BC. Hystaspes had earlier fought a battle against them at Vishpauzati. He was reinforced by Achaemenid troops from Rhagae, then attacked and defeated the rebels at Patigrabana and secured Parthia for Darius.
