Jorge Manrique (1440-1479) was a Spanish poet who actively participated in the coflicts of the era of Juan II. Hew fighted on the side of Isabella of Castile, but during the defense of his right to become the king he died in a battle.
When he wrote love poetry, he used terms like "a battle" and "the war" to describe how to conquest a women. Among other genres, he also wrote about the death.
His most famous book is called Coplas por la muerte de su padre (Verses about the death of his father), which was obviously "mi padre" (my father) in the original, but is generally known under this modified name. He decided to wrote Coplas from his admiration of his father after he died in a battle. For him, he was an example of life and a great hero. Not only Manrique popularized the verse metric refered in spain as Copla de pie quebrado (8a 8b 4c 8a 8b 4c), but he also introduced a new concept of three types of life:
The newly introduced type of life, the life of the fame, means that even dead people continue to live in the memories of the great acts they did when alive.
The language Manrique use was precise, exact, without decoration and difficult metaphors, trying to focus on the cotent of what he was trying to say.

Nuestras vidas son los ríos Our lives are the rivers que van a dar en la mar, that give to the sea, qu´es el morir. what is to die. Allí van los señoríos Here go the reigns derechos a se acabar rights to terminate e consumir. and absorb.
