Short answers, pulled from the story.
Juan del Encina was a Spanish composer, poet, priest, and playwright born on the 12th of July 1468 near Salamanca. He is credited, alongside Gil Vicente, as the founder or patriarch of Spanish drama. His fourteen dramatic pieces mark the transition from purely ecclesiastical to secular theater in Spain.
His birth name was Juan de Fermoselle. He changed his name to Juan del Encina, meaning holm oak, while serving as a chaplain at Salamanca Cathedral in the early 1490s. He also spelled the name Enzina, but both spellings represent the same sound.
Encina composed primarily villancicos, the Spanish equivalent of the Italian frottola, with some sixty or more songs attributed to him along with nine additional text settings. He also wrote fourteen dramatic pieces, including pastoral eclogues. No religious musical compositions of his are known to survive.
Encina worked at Salamanca Cathedral, in the household of Don Fadrique de Toledo the second Duke of Alba, in Rome serving several cardinals, and at Malaga Cathedral where Pope Julius II appointed him Archdeacon in 1508. His final post was as prior of Leon Cathedral, which he held from November 1523 until December 1529.
Yes. Encina traveled to Jerusalem in 1519 and sang his first mass there. He wrote an account of the journey titled Tribagia o Via Sacra de Hierusalem, published in 1521.
Encina is thought to have died in late 1529 in Leon. His will was presented on the 14th of January 1530, so the exact date is uncertain. He requested burial beneath the choir of Salamanca Cathedral, and in 1534 his remains were moved there.
