Archaeologists have unearthed 2,000-year-old mummies with golden tongues placed inside their mouths in northern Egypt, the antiquities ministry says.

An Egyptian-Dominican team working at Alexandria's Taposiris Magna temple discovered 16 burials in rock-cut tombs popular in the Greek and Roman eras. Inside were poorly-preserved mummies.

It is thought the dead were given gold foil amulets shaped like tongues so that they could speak before the court of the god Osiris in the afterlife.

Ancient Egyptians believed that Osiris was lord of the underworld and judge of the dead. The god was also pictured in gilded decorations on the cartonnage - a material made of layers of plaster, linen and glue - that was partially encasing one of the mummies, lead archaeologist Kathleen Martinez of the University of Santo Domingo was cited by the antiquities ministry as saying.

The gilded decorations on the cartonnage around a second mummy's head depicted a crown, horns and a cobra snake, she added. On the chest, the decorations depicted a necklace from which hung the head of a falcon - the symbol of the god Horus.
