Who is Astraea?

Astraea is the goddess of justice. She is the woman blindfolded holding the sword (a little know symbol for justice) and scales that graces many of our tribunals. Each is her pagan temple.
More accurately, she is portrayed with a sword (righteous justice) and wings (swiftness). Sometimes, even in battle-armor. (I suppose she's not as docile as some of the Greco-Roman art depicts).

She is also the woman often portrayed with wings and a sheaf of wheat in the astrological sign of Virgo, the virgin. She is astra is the maxim "Ad astra per aspera", the star symbolizing excellence that people aspire for. She is a star-goddess, not unlike Varda (Elbereth) in the stories of Tolkien.
