[Biographical update of Licentiate Martín de Castellanos de Maudes (1545?-1614). New documented information]

The semblance and facts of licentiate Martín de Castellanos from Maudes (1545-1614?), a novelist surgeon specialized in treating urological diseases and who due to his merits and prestige was appointed professor of 'Urology' by Philip II, were almost definitively profiled in 1994 through the publication of his biography in a exhaustive piece of work.

Thorough review of new documentary findings at the Santa Cruz Church in Madrid and at the Simancas General Archive regarding new biographical information on Martín de Castellanos.

It demonstrates the existence of other children from his marriage and that his eldest son, a collegiate at the University of Salamanca died as a result of the injuries he sustained following a sword fight among students on 13 November 1595. The work provides abundant information on the process that occurred at the University of Salamanca as a result of the death of Castellanos' son, of the lawsuit he filed against the culprits, and of the intervention of Philip II himself at the request of the surgeon, by means of a written order to the city magistrate.

Although the transcription of the documents does not modify the fundamental facts of his life, they do give information on this occurrence, which updates his biography and directly associates the urologist with the king.
