No long ago I saw a story on TV news that the skull is missing from the grave. ...
Yes. Horrible.
Freaky coincidence--know who else died April 23, 1616? (or buried, anyway)--
Miguel de Cervantes.
They did a dig last year and found his missing bones--they reinterred the bones, and built a new monument--
Madrid's outgoing mayor,
Ana Botella, read aloud an inscription on Cervantes' new gravestone — some of the last words the author penned in 1616, in his last novel
The Trials of Persiles and Sigismunda, written just before his death:
Time is brief,
anxieties grow,
hopes diminish,
and yet my desire to live
keeps me alive.
FYI--the new stone monument included a typo! Should have been Sigismunda not Segismunda. Oh well!
