Crocodiles, like snakes, are simultaneously fearsome, dangerous creatures and potent symbols of spiritual and psychic protection. Pregnant Isis, after all, hid in the crocodile infested swamps of the Nile Delta. It was the safest spot she knew.

In ancient days, the papyrus plant, which once lined the Nile, was a hieroglyphic emblem for Lower Egypt, especially that Nile Delta swampland. It also served as a protective emblem from crocodiles, lending new meaning to Moses’ cradle on the Nile, formed from papyrus.  This symbol (shown below) can be used in a variety of ways to create a protective talisman.

• Draw the hieroglyph on parchment paper and carry it.
• For intensive protection, draw the hieroglyph onto the body with henna, or if danger is constant, consider a tattoo.
• Carry a photograph of living papyrus plants as a talisman or post it in a prominent location.

The Egyptian Book of the Dead suggests carrying the plant sweet inula to ward off crocodiles both living ones and those that haunt the spirit realm.

• Wear it in a charm bag to protect against actual visitations.
• Sleep with the herb in a dream pillow or beneath your pillow if unfriendly crocodiles are infesting your dreams.

From Burma we have this tidbit:

• Carry iron pyrites as a protective charm against crocodiles.

Crocodiles shed their teeth, continually growing new ones. Naturally shed teeth have a prophylactic effect: string them and wear on necklaces and anklets to prevent attack. Alternatively, carry the teeth in a medicine bag.

To make a crocodile charm bag, place a piece of gold pyrite into a drawstring bag together with crocodile teeth and/or an image of a crocodile. Carry for protection.
