White Particles on the Turin Shroud
We have explored by optical microscopy and scanning electron microscopy coupled with energy dispersive X-ray about one hundred and fifty particles of white pigments located in a sample of the Face area of the Turin Shroud. Twenty-one of them are micro-fragments of marble. Thirty-two of them are particles of different Coccolith species of chalk. More than fifty of them are ceruse micro-plaques and four are ceruse plaques (yellow in colour); about …
Iron-Rich Red Clays on the Turin Shroud
We have explored by optical microscopy and scanning electrons microscopy coupled with energy dispersive X-ray fifteen particles located in a sample of the Face area of the Turin Shroud. They have the following peculiarities: they are alumino-silicate clays, with an elevated content (up to 56%) of iron; their sides are comprised between 1.5 μm and 19 μm; their forms are rounded or more elongated, but more often with angular outlines. When observab…
Lapis Lazuli Particles on the Turin Shroud
We have studied by optical microscopy and SEM-EDX lapis lazuli particles adhering to a sample of the Turin Shroud. A total number of seventy lapis lazuli particles (and sub-particles) were found on the surface of this sample, and were characterized in details: they are little particles (of between 0.1 and 15 μm of maximal length), of blue colour, and with a spectrum of chemical elements identical to that of the lapis Lazuli mineral. We hypothetis…
Gold and Silver Particles on the Turin Shroud, Studied by Scanning Electron Microscopy and Elemental Analysis
We have studied by optical microscopy and by SEM-EDX some metallic particles of gold and silver adhering to a sample of the Turin Shroud. A total number of eighteen particles (and sub-particles) containing these two elements were characterized in details. Three of them (e49, b22 and h28-0) are parts of gold scales, and six (l38-1, 2, 3, 4, 7’ and 12) are micro-grains of a gold powder. The three a23-1, 2 and 3 sub-particles are the metallic parts …
Radiodating of the Hairs of the Presumed Holy Maria-Magdalena
We report here the result concerning the radiodating of the carbon of the keratin of hairs from a lock of the presumed Holy Maria-Magdalena kept in the Saint-Maximin basilica. The aim of this research is to establish the best dating possible. The age obtained is 1260 ± 30 years; for this hair lock this date corresponds in fact to that of the exhumation of Maria-Magdalena’s body by Charles II in 1279. We conclude that King Charles II had completel…
The Y-SNP Z-381 Is a Patrilineal DNA Marker of the Royal Bourbon Family of France
More than 1100 unrelated males from West-Europe were analysed by molecular hybridization experiments for the p49, f Taq I polymorphisms, and by polymerase chain reaction for the R-S21 and Z381 Y-SNP markers. The corresponding two SNP haplogroups showed similar packty frequency distribution patterns centred on Belgium, the Netherlands, Denmark and the north of Germany. Louis XVI, the last French King, is Z381+. A complete corrected Y-STRs profile …
Scanning Electron Microscopic Characterization and Elemental Analysis of One Hair Located on the Face of the Turin Shroud
As a contribution to the scientific knowledge of the Turin Shroud, we have studied by SEM-EDX a small hair fragment (14 × 9 μ) contained in a blood stain located in the Face between the two eyebrows. SEM study of this fragment shows the typical human scale hair pattern. EDX analysis of the fragment indicates that it is mainly made of organic matter, plus a little sulphur peak. The hair fragment was at both cut extremities with a razor blade forme…
Skin Debris on the Face of the Turin Shroud
Aim: We have studied the only found three skin debris (P1, P2 and P3) deposited on the Face area of our sample of the Turin Shroud. Methods: P1, P2 and P3 were explored by optical microscopy, by SEM and by EDX analysis. Results: All P1, P2 and P3 are true skin debris, as observed in optic and electronic microscopy; their elementary compositions show organic matter, plus a sulphur peak that corresponds to keratin. P1, P2 and P3 are constituted of …
The Major Y-Chromosome Haplogroup R1b-M269 in West-Europe, Subdivided by the Three SNPs S21/U106, S145/L21 and S28/U152, Shows a Clear Pattern of Geographic Differentiation
More than 2600 unrelated males from West-Europe were analysed by molecular hybridization experiments for the p49a,fTaq I polymorphisms. A total of 895 subjects (34%), belonging to haplogroup M269, were identified and further analysed for the three SNPs, S21/U106, S145/L21 and S28/U152; these three SNPs define the Northwest, West and South European sub-haplogroups, respectively. These haplogroups showed quite different frequency distribution patte…
Exploration of the Face of the Turin Shroud. Pollens Studied by SEM Analysis
We studied by SEM-EDX analysis the pollens on the Face of the Turin Shroud. A total of ten pollen grains were found; they were photographed, characterised and analysed. Three of them (pollens p6, p7 and p10) belong to Ceratonia siliqua, the carob tree; one of them (pollen p1) belongs to Balanites aegyptiaca (the palm tree of the desert), and another one (pollen p9) belongs to Cercis siliquastrum (the Judean tree). These three plants have their ge…
North African Berber and Arab Influences in the Western Mediterranean Revealed by Y-Chromosome DNA Haplotypes
We have analyzed Y-chromosome diversity in the western Mediterranean area, examining p49a,f TaqI haplotype V and subhaplotypes Vb (Berber) and Va (Arab). A total of 2,196 unrelated DNA samples, belonging to 22 populations from North Africa and the southern Mediterranean coast of occidental Europe, have been typed. Subhaplotype Vb, predominant in a Berber population of Morocco (63.5%), was also found at high frequencies in southern Portugal (35.9%…
Y-Chromosome DNA Haplotype XI in Eastern Europe
Haplotype XI frequencies at the Y-chromosome-specific DNA polymorphism (p49-TaqI) were reported in 639 males originating from 13 different geographic locations in Eastern Europe, where haplotype XI represents the major haplotype. The highest frequencies were obtained from Ukraine (44%), Russia (43.9%), and Hungary (40.7%). Percentages of haplotype XI geographic distribution show a gradient of decreasing frequency from these areas of higher percen…
North African Genes in Iberia Studied by Y-Chromosome DNA Haplotype 5
The frequency of haplotype 5 at the Y-chromosome-specific DNA polymorphism (p49/TaqI) was reported in a study of 487 males originating from five different geographic locations in Iberia and North Africa. The highest frequency of haplotype 5 (68.9%) was previously observed in Berbers from Morocco, and it has been established that this haplotype is a characteristic Berber haplotype in North Africa. The relative frequencies of haplotype 5 distributi…
Polymorphisme de restriction de la sonde ADN P49 du chromosome Y dans les populations africaines pygmées et bantoues
THE P49/TAQI Y-SPECIFIC CHROMOSOME POLYMORPHISMS IN AFRICAN PYGMIES AND BANTUS Summary. — The DNA probe p49, Y chromosome specific, was used to detect the Taq I restriction polymorphism in two African Pygmies and Bantus populations. Pygmies are characterized by the preponderence of haplotype XIII, and some haplotypes (as the XVIII) are also Pygmies-specific. They are truly distinct for that system from the Bantus populations, and calculation of g…
