The battle is only recorded in two later sources, the Aragonese and Latin versions of the Chronicle of San Juan de la Peña. The former says that "in the year of our Lord 1083 ... [Sancho Ramírez] did battle in Piedra-pissada with the Moors on Christmas day." The Latin translation reads: "And [Sancho] made battle before Petram Pisadam with the Moors, the day of the Nativity in the year of our Lord 1084." The two texts differ in the year, and neither specifies the winner of the engagement. The location of Petra Pisata was long thought to be Piedratajada, but this is unlikely on linguistic grounds. In a document nearly contemporary with the battle, Peter I of Aragon and Navarre, Sancho's son and successor, enumerated the parishes whose tithes belonged to the church of Santa María of Alquézar
