Manuel Argüello Mora was born in San José, Costa Rica in 1834. He is one of the foremost Costa Rican authors, and with 1888's Misterio, was its first novelist. He obtained his education at the University of Santo Tomás in Costa Rica and the Universidad de San Carlos in Guatemala, where he obtained a degree in law. Orphaned at a young age, he was brought up by his uncle Juan Rafael Mora Porras, the president of Costa Rica between 1849 and 1859, and his historical novel La trinchera recounts Mora Porras' campaign against William Walker's forces in Nicaragua in 1856. After Mora Porras was deposed, he followed his uncle into exile in Europe in 1859. He returned in 1860 during Mora Porras' attempt to regain power, and was spared from the firing squad which executed the former president. Between
