The Anthem
Gernikako arbola is also the title of a song (in bertso form) presented in Madrid (1853) and by the shrine of both Saint Anthonies at Urkiola (1854) by the Basque bard José María Iparraguirre, celebrating the tree and Basque freedom. The song is an unofficial anthem of the Basques, besides the official Eusko Abendaren Ereserkia. It has been called the "Marseillaise of the Basques".
The tree has also inspired a passage of La prudencia en la mujer by the Spanish playwright Tirso de Molina and a sonnet of William Wordsworth.
