Lydia

St. Lydia is the patron saint of dyers, sellers of purple cloth, and the city of Thyatira. She is also recognized as a patron of businesswomen and women in general.

Battle of Thyatira happened in 366.

Saint Lydia was a merchant of purple cloth in Thyatira who became one of the first Christian converts in Europe. She welcomed the Apostle Paul into her home in Philippi and was instrumental in the establishment of the early Christian community there. She is considered a patron saint of dyers, and her feast day is celebrated on August 3rd.

She was a seller of purple dye, which (in those days) was a profitable, "high-class" business. (Only Roman citizens could wear a toga with a purple border, etc.).
