Matrona of Barcelona was a third-century Christian saint born in Barcino. Serving as a slave to a woman named Pautila, who was married to a military leader or governor in Thessaloniki, she maintained her Christian faith despite constant pressure to convert to Judaism. Her life ended in martyrdom, though accounts of her death vary. One tradition claims she was executed in Rome for assisting other Christians, while another suggests she died from injuries sustained after refusing to accompany her mistress to a synagogue.
