His most famous work is "Elegías de varones ilustres de Indias", a 40-canto poem that tells the story of the Spanish conquest of Venezuela, Colombia, and Ecuador.
Here are some other works by Juan de Castellanos:
* "Historia del Nuevo Reino de Granada": A prose account of the conquest and settlement of Colombia.
* "Cancionero y elegías": A collection of poems on various themes, including love, war, and religion.
Castellanos's works are important not only for their literary merit but also for their historical value. They provide valuable insights into the lives and experiences of the people involved in the Spanish conquest of South America, both Spanish and indigenous.
