As well, the Friends raise funds towards the conservation, publication and display of the Petrie Museum's outstanding collection. Organisation and collections The museum is split into three galleries. The main gallery (housed above the old stables) contains many of the museum's small domestic artefacts, mummy portraits and cases, and the Inscriptions Aisle. The Inscriptions Aisle displays tablets, including Pyramid Texts, written in hieroglyphics, hieratic, Greek, and Arabic, and organised according to material type. Another gallery (the pottery gallery) contains many cabinets of pottery, clothing, jewellery, and shabti figures, arranged chronologically. A new entrance gallery was refurbished in 2019 which provides an insight into the history of the museum, its collections, and notable figures. The entire collection has been digitised and the catalogue can be browsed and consulted online. Notable holdings The collection contains some significant 'firsts': one of the earliest pieces of linen from Egypt (about 5000 BC); two lions from the temple of Min at Koptos, from the first group of monumental sculpture (about 3000 BC, these are located outside the provost's office in the Wilkins Building on Gower Street); a fragment from the Palermo Stone (first kinglist or calendar, about 2900 BC); the earliest example of metal from Egypt, the first worked iron beads; the earliest 'cylinder seal' in Egypt (about 3500 BC); the oldest wills on papyrus paper; the oldest gynaecological papyrus and the only veterinary papyrus from ancient Egypt (access available upon request); and the largest architectural drawing, showing a shrine (about 1300 BC). Costume is another strength of the collection. In addition to the Tarkhan Dress (the 'oldest dress') there is a unique beadnet dress of a dancer from the Pyramid Age (about 2400 BC), two long sleeved robes of the same date, a suit of armour from the palace of Memphis, as well as socks and sandals from the Roman period. The collection contains works of art from Akhenaten’s city at Amarna: colourful tiles, carvings and frescoes, from many other important Egyptian and Nubian settlements and burial sites. The museum houses the world’s largest collection of Roman period mummy portraits (first to second centuries AD). The collection also includes material from the Ptolemaic, Roman and Islamic periods. There is a substantial archive held in the museum, including excavation records, correspondence and photographs relating to excavations led by Flinders Petrie. There are additionally documents relating to the distribution of finds from fieldwork to museums worldwide
