Who was Lydia?

 Lydia was the first gentile European convert to Christianity and was probably the richest commoner mentioned in the Bible. She was a merchant in Thyatira (in modern Turkiye) who sold purple cloth, an expensive luxury item which was only available to the very wealthy and especially to members of the royalty. The purple dye used was extracted from a special sea mollusk. Less well-off people used red dyes while most probably used no dyes at all. Lydia allowed Paul and Silas to use her home as a house church.

Acts 16:14-15.
