The third caretaker, Manuel Loayzaga, was the man responsible for giving the shrine the appearance it has today.
Just as importantly, Loayzaga put the final, "official" version of the Ocotlán legend into print, publishing two editions of his book Historia de la milagrosíssima imagen de Nuestra Señora de Occotlán (sic) in 1747 and 1750.
