ARe there any records of Romans crucifying women as a punishment?
Yes, though it appears to have been rather rare.
Josephus’ *Antiquities *(Book 18) mentions a woman named Ide was crucified by Tiberius.
Romans also sometimes executed slaves en masse and it is certainly reasonable to conclude the woman would have been included in those numbers.
Historians tend to think that Roman society was repulsed by crucifixion and therefore not many authors would be likely to want to record its happening for posterity. It was an extreme form of punishment used for what they considered extreme cases (treason, rebellion, sedition, etc). These aren’t normally the kinds of crimes that women would have had the opportunity to take part in.
