National Lydia Day

Acts 16 introduces a dealer in purple cloth from Thyatira. She hears Paul preach beside a river at Philippi and is baptised with her whole household. The Episcopal Church's own service book calls her Paul's first European convert.

The safer wording is first documented convert. That is a claim about what survives in writing, not about who reached Europe first. The same service book notes she is never mentioned by name anywhere outside Acts.

Her name reads as an ethnicon, a label for where a person came from rather than a name in its own right. Behind the Name gives the modern name that same reading: from Lydia, after a region on the west coast of Asia Minor.

The gloss on baby name sites says something warmer, beautiful one or noble one. Wiktionary, which prints that gloss, traces it to an Ancient Greek word it has no entry for.

English speakers have used the name since the Protestant Reformation. Novelists and reformers have both reached for it since. Jane Austen gave it to a Bennet sister in Pride and Prejudice.

Lydia Maria Child, an abolitionist, signed it to a book advocating education for Black Americans. Lydia Becker signed it to a suffrage journal she ran out of Manchester. The day that now sits on the calendar for all of them arrived from nowhere anyone can point to.
