Radiocarbon dating of the Liber Linteus Zagrabiensis

Radiocarbon dating of linen cloth fragments of the Zagreb mummy wrappings without Etruscan inscriptions resulted in a mean Libby age equal to 2290 +- 48 years BP. Dendrochronological correction in fairly reliable for the period between 2200 and 2400 years BP which made it possible to set the true calendric age of 390 +- 45 years BC. Besides the linen cloth, other datable materials associated with the mummy were the embalming unguent and leaves. The unguent used in embalment procedure has unacceptably old radiocarbon age owing to a CHCl3 soluble fraction, probably fossil resins and/or mineral oils, themselves much older. After extraction with CHCl3, the insoluble residue consists of charred fragments of leaves and branches, practically contemporaneous with the linen, as judged by its radiocarbon age. Leaves are also of the same radiocarbon age, however the statistical error has been much larger because of small quantity of available material. Various analyses or identifications of the associated material such as chemical microanalysis (C, H, N), IR and NMR measurements, pollen analysis and paleobotanical identification of leaves had been made possible through generous cooperation of many experts and institutions.
