Juan del Encina – (July 12, 1468 – 1529 or 1530) was a composer, poet, and playwright, often called the founder, along with Gil Vicente, of Spanish drama.
His birth name was Juan de Fermoselle.
He spelled his name Enzina, but this is not a significant difference; it is two spellings of the same sound, in a time when "correct spelling" as we know it barely existed.
