This is one of the canopic jars belonging to a woman called Tjuyu made out of Egyptian alabaster with a small gold coffinette inside in which her mummified internal organ was placed. I think it may be the one that contained her intestines, as I think it mentions the deity Serket.
She was married to a man called Yuya, and they were the parents of Tiye who was the Great Royal Wife of Amenhotep III and mother of Akhenaten. Their tomb was in the Valley of the Kings, KV46, and was discovered robbed but still with many of its grave goods in 1905.
I always find the alabaster objects from Ancient Egypt eye-catching, particularly when the inscriptions are picked out in ink like this one is. It’s something about the juxtaposition of the creamy rounded stone that looks almost soft, and the crisp neat text on it.
This is now in the Cairo Museum with the rest of the contents of their tomb (acc. no. JE95244).
