Colombian literature dates back to pre-Columbian era; a notable example of the period is the epic poem known as the ''Legend of Yurupary''. In Spanish colonial times, notable writers include Juan de Castellanos (''Elegías de varones ilustres de Indias''), Hernando Domínguez Camargo and his epic poem to San Ignacio de Loyola, Pedro Simón, Juan Rodríguez Freyle (''El Carnero''), Lucas Fernández de Piedrahita, and the nun Francisca Josefa de Castillo, representative of mysticism.
