Short answers, pulled from the story.
Ausiàs March was a Valencian poet and knight born around 1400 in Gandia, who died on the 3rd of March, 1459, in Valencia. He is considered one of the most important poets of the Valencian Golden Century and was among the first to write major poetry in Valencian rather than the troubadour language, Occitan.
Ausiàs March wrote three groups of poems: the Cants d'amor (love songs), the Cants de mort (death hymns), and the Cant Spiritual. The Cant Spiritual is considered the apex of his central conflict between desire and moral conviction.
Ausiàs March wrote in Valencian, the local vernacular, rather than Occitan, the troubadour language that had dominated the tradition before him. He was among the first poets in his region to make this shift, helping establish Valencian as a serious literary language.
March's success in adapting Italian metres to Valencian verse inspired the poet Boscán to introduce those same forms into Castilian. His use of Petrarchan rhetoric for deep psychological meditation also anticipated work by poets including Camões and Shakespeare.
The poems of Ausiàs March first appeared in a Spanish translation in 1539, more than eighty years after his death. The first Valencian-language printed edition followed in 1543; before both dates, his verse had circulated only in manuscript.
Ausiàs March was the son of Pere March, a poet and treasurer to the Duke of Gandia, and Lionor of Ripoll. His uncle, Jaume March II, was also a poet. He had a younger sister named Peirona, and was twice married: first to Isabel Martorell, sister of the writer Joanot Martorell, and later to Joana Escorna.
