Peter González Telmo, OP (1190 – 15 April 1246), also known as Saint Elmo, was a Castilian Dominican friar and priest, born in 1190 in Frómista, Palencia, Kingdom of Castile and Leon.

On one occasion, he was riding triumphantly into the city, his horse stumbled, dumping him into the mud to the amusement of onlookers.

After King Saint Ferdinand III of Castile and Leon captured Córdoba, González was successful in restraining the soldiers from pillaging the city.

[2] After retiring from the court, González devoted the remainder of his life to preaching in northwest Spain, and developed a special mission to Spanish and Portuguese seamen.

[1] The diminutive "Elmo" (or "Telmo") belongs properly to the martyr-bishop Erasmus of Formia (died c. 303), one of the Fourteen Holy Helpers.
