The lauburu (Basque: lau ("four") + buru ("head")) is an ancient hooked cross with four comma-shaped heads and the most widely known traditional symbol of the Basque Country and the Basque people. In the past, it has also been associated with the Galicians, Illyrians and Asturians.
A variant of lauburu consisting of geometrically curved lines can be constructed with a compass and straightedge, beginning with the formation of a square template; each head can be drawn from a neighboring vertex of this template with two compass settings, with one radius half the length of the other.
Historians and authorities have attempted to apply allegorical meaning to the ancient symbol of lauburu. Augustin Chaho said it signifies the "four heads or regions" of the Basque Country. The lauburu does not appear in any of the seven historical provinces' coats-of-arms that have been combined in the arms of the Basque Country: Biscay, Gipuzkoa, Araba, Upper Navarre, Lower Navarre, Labourd, and Soule. While some authors have suggested that the four heads of lauburu could signify, e.g., form, life, sensibility, and conscience, lauburu is more generally considered just a symbol of prosperity and good fortune.
Louis Colas considers that the lauburu is not related to the swastika but comes from Paracelsus and marks the tombs of healers of animals and healers of souls (i.e., priests). Around the end of the 16th century, the lauburu appears abundantly as a Basque decorative element, in wooden chests or tombs, perhaps as another form of the cross. Straight swastikas are not found until the 19th century.
Many Basque homes and shops display the symbol over the doorway as a sort of talisman. Sabino Arana interpreted it as a solar symbol, to support his own theory of a hypothetical Basque solar cult (based on etymologies that have later been shown to be incorrect) in the first issue of the daily newspaper Euzkadi in 1913.
The lauburu has been featured on flags and emblems of various Basque political organisations including Eusko Abertzale Ekintza (EAE-ANV).
