The Thaïs Bone is an engraved - or notched - bovine rib fragment, discovered in The Thaïs cave (Grotte de Thaïs, variants Thaï/Taïs/Taï) in Saint-Nazaire-en-Royans, Département de la Drôme, France.[1]
The object dates from the end of the last Ice Age - around 12,000 years ago - having been created by people of the early Azilian culture, of the early Mesolithic period (sometimes referred to as Azilian-Epipalaeolithic).
It has been on display at the Musée de Valence since 2006.[2]
Significance
[edit]The composition of markings on the Thaïs bone represent the most elaborate time-factored sequence currently known within mobile Palaeolithic art.[3]
In 1991, the American archaeologist Alexander Marshack demonstrated that the notches were not a decorative representation, but a system for recording time. He conducted meticulous analysis of the bone fragment during the 1970s and 80s, and a comparative study of one hundred European notched bones. He proposed that the engraved notches corresponded to the notation of lunisolar astronomical observations, and constituted one of humanity's first calendars.[4]
Discovery and studies
[edit]The bone was discovered during excavations carried out in the Thaïs cave, between 1968-69, by two locals from Drôme: Jacques Léopold Brochier, an archaeologist, and his cousin Jacques-Elie Brochier (it was then called the Taï cave).[2] Prior to this a limited exploration of the cave was undertaken in 1878, facilitating access to the water-filled galleries.[1] The Brochiers conducted initial studies on the bone fragment during the early 1970s; analysis continued in stages over the next twenty years,[4] with the substantive analysis and interpretation carried out by Alexander Marshack.[1]
The notched bone artefact was found among the remains of marmots and ibex. It forms part of a large archaeological set of engraved bones and pebbles deposited at the end of the Last Glacial Period (LGP) - during a period of prehistoric fauna and megafauna migration.[2]
The Thaïs cave is situated close to the Campalou rock shelter (Abri de Campalou), at an elevation of 220m AMSL.[1] This contains a rich archaeological layer dating to the Late Magdalenian (12,800 ± 300 BP) and Epipalaeolithic-Azilian, where engravings of other bone artefacts have also been found.[3]
Description and interpretation
[edit]The Thaïs Bone fragment measures 87mm × 27 mm, and is engraved on both faces.
The composition consists of a boustrophedon sequence of short horizontal containing lines or sections, each of which carries irregular subsets of marks; none of the carvings could have occurred naturally.[1]
The engravings are non-decorative, and represent a complex, cumulative, non-arithmetical notational system of time-reckoning, and recording, based upon daily lunisolar observations - over the course of as much as 3.5 years.[1][3]
The shape of the overall pattern suggests that the sequence was kept in step with the seasons by observations of the solstices.[1]
The process of aligning the lunar phase (month) with the seasons of the solar - or tropical - year within lunisolar calendars is called intercalation.
According to the calendrical analysis the accumulation of notations on the bone therefore represent a form of visual cueing and problem-solving.[4].
The complex nature of the markings, coupled with their proposed calendrical purpose carries profound implications for the understanding of European early Mesolithic (Azilian-Epipalaeolithic) culture,[4] and within the fields of archaeoastronomy, and the history of art, calendars, and chronometry.
