Tommaso da Olera, born Tommaso Acerbis, was an Italian Capuchin friar who lived from 1563 to 1631. Raised in a poor family, he worked as a shepherd before joining the Order of Friars Minor Capuchin in 1580. He spent much of his religious life serving in various locations, including Verona, Vicenza, and Rovereto, before eventually moving to Austria. Known for his humility, he acted as a spiritual guide to several notable figures, including Archduke Leopold V and his wife, Claudia de' Medici.
