Alonso Álvarez de Soria

Alonso Álvarez de Soria (1573–1603) was a Spanish adventurer and poet of the Spanish Golden Age. He was known as el Tuerto (the One-Eyed). His short but eventful life ended on the gallows.

Life Soria was born in Seville in 1573. He went to the Americas as a soldier (1595–1596) before returning to Seville.

As a satirical poet, Soria associated closely with the literati of Seville. Soria's works are frequently confused with those of Góngora and Quevedo. He had a reputation as a womanizer, and served as the model for the seducer Loaysa in Cervantes' El celoso extremeño (The Jealous Extremaduran). He also appeared in Cervantes' Viaje del Parnaso (Journey to Parnassus).

In 1603 Soria invented versos de cabo roto, a form of poetry in which the last (unstressed) syllable of each line is truncated. Several of Cervantes' poems in the prologue to Don Quixote are in this form, which "enjoyed some transitory popularity."
