The "Lauda de Aroaldo" tombstone was discovered during cathedral excavations between 1946 and 1959. It was found broken in two, near the apostolic edicule, and was part of the cemetery at the Basilica of Alfonso II in its final years.
It is a roughly made epigraphic piece in a slightly curved trapezoid shape. This inscribed tombstone is the oldest of all those found in the cathedral, after that of Bishop Theodemar. The inscription's layout is also unique, forming a single horizontal band in the center covering nearly the entire piece.
All this, together with its shape and design, allow us to date this tombstone to a time of transition from "double stole" to epigraphic styles, and even from the Gallaecia of Late Antiquity to medieval Galicia.
