Terra or Tellus was a primeval Roman goddess, mother of Fama. Her festival was held on April 15; it was called the Fordicia. Pregnant cows were sacrificed. From January 24 to 26, the Sementivae in honor of Terra and Ceres was held. The Goddesses were asked to protect sowers and seeds. She was seen as the goddess of the earth, fertility, motherhood and pregnant women. http://en.wikipedia.org/wiki/Tellus
