"The Gospel according to Mark" (originally in Spanish "El Evangelio según Marcos") is a short story by the Argentine writer and poet Jorge Luis Borges.
Baltasar Espinosa, a kindly but indifferent young medical student on holiday, gets trapped alone at his cousin's ranch in the Argentinian countryside during the rainy season.
To pass the time he begins reading to the Gutres, the illiterate farm family that works at the house, though out of the few books available the only one that manages to keep their attention is a old dusty Bible.
The Gutres family is captivated by the Gospel According to Saint Mark, which they are unfamiliar with, and ask Espinosa to read it to them repeatedly.
The Gutres family becomes increasingly reverential towards Espinosa thanks to his Gospel readings and the assistance he provides, including treating an injured lamb cared for by the foreman's daughter.
