La Celestina
Rojas studied law at the University of Salamanca, graduating around 1498. While at the university he began writing "La Celestina" (originally titled "Tragicomedia de Calisto y Melibea"), which was published in 1499. The work has been variously described as a drama, a dramatic poem, a dialogued novel, a novel-drama, and as 'ageneric' – a genre entirely of its own. It was never staged during Rojas's lifetime, but the majority of modern scholars consider it a drama. It describes a love affair, with much bawdy and comic detail, before a tragic ending. The scholar Dorothy Severin has written that it may be considered as either the last Spanish work of the Middle Ages or the first of the Renaissance. As far as is known it is Rojas's only work of literature or drama. The writer Keith Gregor calls "La Celestina" "vastly influential" but "his only literary testament".
