Although most scholars admit that an earlier version by an unknown author already existed, the first known edition is credited to be the "Comedy" published in Burgos by printer Fadrique Aleman in 1499 with the title "Comedia de Calisto y Melibea" (Comedy of Calisto and Melibea). It is preserved in the Hispanic Society of New York City. On its first page it states: "nuevamente revista y enmendada con la adición de los argumentos de cada un auto en principio" ("newly reviewed and amended with the addition of the synopses of each act at its beginning"), alluding to a princeps edition prior to 1499.
