Writing Tablet Amulet

Writing tablet of green fedspar. Roughly made of azurite. Was positioned lying on the breast of the mummy in the thoracic region. 1 of 32 amulets removed from a mummy on 8 December 1966 at Aintree University Hospital. The mummy was in a damaged state and it's accession history had been lost. The mummy was first X-rayed then cut apart for research purposes. The mummy was thought to be Ptolemaic as the arms of the mummy were crossed. Maybe from a 21st Dynasty coffin from the Mond collection (later reuse?).
