Encyclopedia entry

Brigit (Brigid, Bride, Banfile), which means the Exalted One,
was the Celtic (continental European and Irish) fertility
goddess.  She was originally celebrated on February first in
the festival of Imbolc, which coincided with the beginning
of lactation in ewes and was regarded in Scotland as the date
on which Brigit deposed the blue-faced hag of winter.  The
Christian calendar adopted the same date for the Feast of St.
Brigit.  There is no record that a Christian saint ever
actually existed, but in Irish mythology she became the
midwife to the Virgin Mary.
