St Bibiana, aka Saint Viviana, is the Patron Saint of Drunks.
Bibiana’s family were Christians in Rome during the persecutions of the Emperor Julian. She was martyred sometime around 361 to 363.
In fact, the only thing we know for sure about her life that is a basilica was consecrated in Rome to her by Simplicius (Pope from 468 to 483) in c. 467. The church is still extant today in Rome, called “Santa Bibiana”, next to the main train station in Rome. The bodies of 3 women (the other two presumed to be her mother Dafrosa and her sister Demetria ) were actually found in a sarcophagus in the church, with a piece of metal in the sarcophagus identifying them by name. Later, stories grew up about her family being persecuted Christians, with the church said to be the site where her house was, etc.
Her name actually names “full of life” (“vivo”), but the Spanish tend to pronounce “v’s” as “b’s”, and thus she became St Bibiana. The “bib” part sounded related to the Latin word “bibere”, “to drink” — where our words such as “beverage” and “imbibe” come from — so it’s by sound association that she got mixed up with drinkers — there’s nothing actually in the story of her life about her carousing around Rome.
