Taweret is the hippopotamus goddess who protects women in pregnancy and childbirth and stands at the birth house with Bes, holding the sa-amulet and a knife, pregnant herself, lion-legged and with a crocodile's tail. She has no myth cycle and no temple of her own; her power is carried on the ivory birth wands, the amulets and the household objects, and as 'Mistress of Pure Water' she also guards the dead into rebirth. In the late temple at Karnak she is one of the hippopotamus mothers of the sun, and she is not Ammit, the devourer.
Modern Practice
Taweret is called in pregnancy, at a birth, and in any rite of protection around a newborn or a new work. The practice is practical: the amulet placed, the room guarded, the knife laid where it can be seen.
