There are Virgin Mary and the Fixed Star Spica, the great gift of mankind.
A particular article about The Star of Bethlehem, Virgo Virgin Mary and the Star Spica: http://www.askelm.com/star/star006.htm
Virgo, The Seed of the Woman. Jesus was born as the flesh of Woman alone with the Spirit from God. A 14 pages article of the Constellation of Virgo and Christianity, of course including Spica: http://biblenumbers.files.wordpress.com/2012/10/virgo-seed-of-the-woman1.pdf
Mythology of Virgo

I cannot find any documentation to support the idea that the Babylonians associated the constellation we know as Virgo with a virgin. To the Babylonians this constellation represents Shala, the Babylonian goddess of agriculture. And even in the Greco-Roman religion Virgo is associated with agriculture and has only a secondary connection to virginity (despite the Roman name Virgo).
