Barbara is a given name used in numerous languages. It is the feminine form of the Greek word barbaros (Greek: βάρβαρος) meaning "stranger" or "foreign". In Roman Catholic and Eastern Orthodox tradition, Saint Barbara (Greek: Ἁγία Βαρβάρα) was imprisoned in a tower by her father. She was then martyred by her father when she refused to renounce Christianity. According to legend, her father was then punished with death by lightning. As such, Saint Barbara is a protectress against fire and lightning.
