Sacred Ibis (Threskiornis aethiopicus) were widespread in Egypt until the eighteenth century. Today the species is extinct in modern Egypt but millions of mummified specimens are scattered geographically in dedicated Ibis burial sites throughout the country. Ibises were regarded as physical manifestations of the god Thoth and worshiped by the ancient Egyptians. A small number of Sacred Ibis were chosen as ‘sacred animals’, based on physical markings, and were reared for the temples. However, the majority of the mummified Sacred Ibis were ‘votive animals’ that were given as offerings to the deities by pilgrims, and then buried in catacombs associated with the temple. Their supply became an industry that is thought to have flourished from the Late Period, well into the Roman Period (c. 664 BC to AD 350). Dating of the Sacred Ibis mummies, as well as other mummified animal specimens, has been based on archaeological evidence such as the age of catacombs, the design of enclosures and the shape of the mummy containers (pottery jars, wooden chests or stone boxes). Here we present the first ages of a selection of Sacred Ibis mummies using 14C methods in order to establish how closely they match the archaeological chronology. Dates are reported from museum samples provenience from Saqqara, Roda and Thebes. Our 14C radiocarbon results date the Ibis mummies between c. 450 and 250 cal BC and represent a short period of time. Those dates are falling from the Late Period to the Ptolemaic Period at maximum. Surprisingly, none of the samples were dated to the Roman era.

Abstract Carbon, nitrogen and sulfur stable isotope compositions were measured in hard and soft tissues from Egyptian mummies of humans and animals in order to track the diet of ancient Egyptians from 5500 to 1500 years B.P. The carbon isotope ratios of bone apatite (δ 13 C bo = −14.3 ± 0.9‰) and hair protein (δ 13 C h = −19.9‰) are compatible with a diet based almost exclusively on C3-derived food (proportion of C4 13 C en = −11.6 ± 0.7‰) relative to bones from the same mummies could be the res...

The funeral preparations for ancient Egyptian dead were extensive. Tomb walls were often elaborately painted and inscribed with scenes and objects deemed desirable for the afterlife. Votive objects, furniture, clothing, jewelry, and importantly, food including bread, cereals, fruit, jars of wine, beer, oil, meat, and poultry were included in the burial goods. An intriguing feature of the meat and poultry produced for the deceased from the highest levels of Egyptian society was that they were mum...

Abstract This paper presents the results of a 14-year study about the diet of the Sacred ibis in its main introduction area in France and its impact on native bird species, and compares the data to literature from its native area. During an initial period (1993–2004), the diet was essentially composed of invertebrates such as common aquatic insects (correlated with flooding) or Eristalis larvae picked from the mud (a vacant food niche in France), while scraps of meat taken from rubbish dumps wer...

Abstract Freshwater resources in past diets can lead to inaccuracies when attempts are made to ascertain their radiocarbon ages or those of the consumers. Radiocarbon reservoir effects may lead to significant age offsets when the bones or other tissues of these consumers are radiocarbon dated. A number of recent studies have investigated freshwater reservoir offsets. However no study thus far has satisfactorily obtained a ubiquitous freshwater reservoir correction due to variability in the ecosy...

The historical chronologies for dynastic Egypt are based on reign lengths inferred from written and archaeological evidence. These floating chronologies are linked to the absolute calendar by a few ancient astronomical observations, which remain a source of debate. We used 211 radiocarbon measurements made on samples from short-lived plants, together with a Bayesian model incorporating historical information on reign lengths, to produce a chronology for dynastic Egypt. A small offset (19 radioca...

Some radiocarbon dates for ancient Egypt have been significantly offset from the established historical chronology (see Bonani et al., 2001). In this paper, short-lived plant species collected in Egypt between 1700 and 1900 AD were used to investigate the possibility that the radiocarbon record had been influenced by reservoir effects. AMS radiocarbon measurements were made on 66 known-age samples, resulting in an average offset from expected values of 19 years. The implications of this minor di...

Lake Mývatn is an interior highland lake in northern Iceland that forms a unique ecosystem of international scientific importance and is surrounded by a landscape rich in archaeological and paleoenvironmental sites. A significant freshwater reservoir effect (FRE) has been identified in carbon from the lake at some Viking (about AD 870?1000) archaeological sites in the wider region (Mývatnssveit). Previous accelerator mass spectrometry (AMS) measurements indicated this FRE was about 1500-1900 14C...

The wide availability of precise radiocarbon dates has allowed researchers in a number of disciplines to address chronological questions at a resolution which was not possible 10 or 20 years ago. The use of Bayesian statistics for the analysis of groups of dates is becoming a common way to integrate all of the 14C evidence together. However, the models most often used make a number of assumptions that may not always be appropriate. In particular, there is an assumption that all of the 14C measur...

The ancient catacombs of Egypt harbor millions of well-preserved mummified Sacred Ibis (Threskiornis aethiopicus) dating from ~600BC. Although it is known that a very large number of these ‘votive’ mummies were sacrificed to the Egyptian God Thoth, how the ancient Egyptians obtained millions of these birds for mummification remains unresolved. Ancient Egyptian textual evidences suggest they may have been raised in dedicated large-scale farms. To investigate the most likely method used by the pri...

The long-term preservation of DNA requires a number of optimal conditions, including consistent exposure to cool, dry, and dark environments. As a result, the successful recovery of ancient DNA from material from warmer climates such as those in Egypt has often been met with scepticism. Egypt has an abundance of ancient mummified animals and humans, whose genetic analyses would offer important insights into ancient cultural practices. To date, the retrieval of complete genomes from ancient Egypt...

In 1798, Napoleon Bonaparte’s army invaded Egypt, returning with many treasures including large numbers of Sacred Ibis mummies. The ancient Egyptians revered the ibis and mummified literally millions of them. The French naturalist Georges Cuvier used these mummies to challenge an emerging idea of the time, namely Jean-Baptiste Lamarck’s theory of evolution. Cuvier detected no measurable differences between mummified Sacred Ibis and contemporary specimens of the same species. Consequently, he arg...

The ancient Egyptians mummified animals as part of cultic activity from the Late Period into the Roman era (7th century BC to the 4th century AD). Necropolises have provided millions of animal mummies, reflecting the religious fervor of Egyptians with regard to sacred animal cults during this period. Despite the number of sites containing mummies, and the number of mummies themselves, surprisingly little is known with regard to the nuances in the dating of the cults’ popularity and activities. A...

Queen Nefertari, the favourite Royal Consort of Pharaoh Ramses II (Ancient Egypt, New Kingdom, 19th Dynasty c. 1250 BC) is famous for her beautifully decorated tomb in the Valley of the Queens. Her burial was plundered in ancient times yet still many objects were found broken in the debris when the tomb was excavated. Amongst the found objects was a pair of mummified legs. They came to the Egyptian Museum in Turin and are henceforth regarded as the remains of this famous Queen, although they wer...
