Oriental dyeing. The Orientals have some very fine dyes. Their favorite color is a bright crimson, and the dye they use to make this color comes from a worm or grub that feeds on oak and other plants. Indigo is made from the rind of pomegranate. Purple is made from the murex shellfish which can still be found on the beach at the city of Acre.
Luke tells of Lydia, "a seller of purple, of the city of Thyatira" (Acts 16:14). She was a merchant who sold the purple dye to tanners, weavers, and others. This business of dyeing with which she was connected, had long been centered in the city of Thyatira. Inscriptions have been discovered that refer to "a guild of dyers" that was located in that vicinity. [Manners And Customs of Bible Lands]
