This is a heart scarab with the 30th chapter of the Book of the Dead incised in hieroglyphs.

It is from Egypt but the exact location is unknown. Egyptians feared that their heart might speak against them after death at the test known as the Weighing of the Heart. Heart scarabs were often placed within the bandages of the mummy to prevent this. They were usually inscribed with Chapter 30 from the Book of the Dead: “O my heart which I had upon earth, do not rise up against me as a witness in the presence of the lord of things; do not speak against me concerning what I have done, do not bring up anything against me in the presence of the great god of the west…”. This is a heart scarab with the 30th chapter of the Book of the Dead incised in hieroglyphs. It is made from jade. It is over 3,300 years old, dating to the 18th, 19th or 20th Dynasty (1550-1295 BCE) in the New Kingdom.
