coffin that faced east in the tomb was decorated with a pair of eyes so that the deceased could look out towards the rising sun with its promise of daily rebirth. Coffins also began to be decorated on the outside with bands of funerary texts, while pictures of food and drink offerings were painted on the inside to provide a magical substitute for the real provisions placed in the tomb. In the First Intermediate Period, decorated coffins became a substitute for tomb decoration; in the Middle Kingdom, coffin texts made their first appearance, sometimes accompanied by detailed maps of the underworld. Middle Kingdom coffins show a number of distinct regional styles, echoing the cultural fragmentation of the preceding period. In the 17th and early 18th Dynasties, the Theban area produced characteristic anthropoid rishi (feathered) coffins. These were replaced (except for kings) by other styles of anthropoid coffins which became the standard form throughout the country for the remainder of Egyptian history. The predominance of decorated tombs in the New Kingdom removed the need of object friezes, so coffins were generally undecorated on the inside. However, this situation was reversed again in the Third Intermediate Period when new types of coffin decoration focused on the Osiris myth and extracts from the Book of the Dead, to aid the resurrection of the deceased. In the Ptolemaic and Roman periods, a cartonnage mask was often fixed directly onto the mummy wrappings as a substitute for a coffin. Coffins were generally made of wood; those of high-status individuals used fine quality, imported cedar. From the Middle Kingdom onward, wealthy individuals were often provided with a set of two or three nested coffins. The most sumptuous coffins might be inlaid with glass or precious stones, while royal coffins were often made from gold or silver. Canopic jars Canopic jars are vessels which were used for storing the internal organs removed during mummification. These were named after the human-headed jars that were worshiped as personifications of Kanops (the helmsman of Menelaus in Greek mythology) by the inhabitants of ancient Canopus. The practice of evisceration is first attested in the burial of Hetepheres in the early 4th Dynasty. Her organs were stored in a travertine canopic chest divided into four compartments. Later, each organ – the liver, lungs, stomach and intestines – was provided with a separate jar, of stone or pottery, and placed under the symbolic
