In today's reading in Acts 16:14, we are introduced to Lydia: "One who heard us was a woman named Lydia, from the city of Thyati'ra, a seller of purple goods, who was a worshiper of God. The Lord opened her heart to give heed to what was said by Paul". Some have surmised from this that Lydia was a wealthy trader in the precious purple dye for which that city was famed. Mention is also made of her household being baptized which again suggests that she was a woman of means.
This mosaic from Ostia Antica gives one a glimpse of what a wealthy woman of Roman times, such as Lydia is said to have been, would have looked like.
