This battle, fought in the mountains of Asturias, was hailed by 19th and 20th century historiography as the start of the Reconquista, the Christian re-conquest of the Iberian peninsula from the Moorish domination.

In 908 the Asturian King Alfonso III the Great ordered that the original wooden cross, made of oak, be clad in gold and precious stones.

This is a direct reference to the Book of Revelation (verses 1:8, 21:6, and 22:13), I am the Alpha and the Omega, the beginning and the end, says the Lord God, who is, and who was, and who is to come, the Almighty.

The banners that might represent the early medieval Kingdom of Asturias are unknown, although a white ensign with a red border and a cross of the same color has been attributed as the royal flag of Ramiro I, as can be seen in tomb A of the Cathedral in Santiago of Compostela.

Gaspar Melchor de Jovellanos, an Asturian intellectual of the Enlightenment, led a note with his findings on the symbols of the Kingdom of Asturias, based on the older description of Lazaro Diaz del Valle an author of 17th Century.
