In the period between 400 to 800 AD, also known as the period of the Barbarian invasions, intense migration is documented in the historical record of Europe. However, little is known about the demographic impact of these historical movements, potentially ranging from negligible to substantial. As a pilot study in a broader project on Medieval Europe, we sampled 102 specimens from 5 burial sites...
The careful description of the solar eclipse of A.D. 1567 by Clavius is used to derive limits to the Earth’s rotational clock error (∆T) of between 145 and 165 sec at this date. This result provides an important link between the ∆T curve as deduced from ancient and medieval eclipse observations and that obtained from telescopic data.
Second-harmonic generation imaging (SHG) captures triple helical collagen molecules near tissue surfaces. Biomedical research routinely utilizes various imaging software packages to quantify SHG signals for collagen content and distribution estimates in modern tissue samples including bone. For the first time using SHG, samples of modern, medieval, and ice age bones were imaged to test the appl...
In the ophthalmological treatises of the medieval Arabo-Islamic physicians such as al-Mawsili (9th-10th century), al-Kahhal (ca. 940-1010), Haly Abbas (10th century) and al Sadili (14th century) we may find references about ocular cancer, focusing on eyelid tumors and cancerous ulcers of the cornea. These references are similar to the analogous ones of ancient Greek physicians as these are pres...
Terms like ‘wisdom’ are commonly held to refer to abstract objects that are properties. On the basis of a greater range of linguistic data and with the support of some ancient and medieval philosophical views, I argue that such terms do not stand for objects, but rather for kinds of tropes, entities that do not have the status of objects, but only play a role as semantic values of terms and as ...
After the boom of pharmacological research during the 1950s, mainly as a result of the screening technique, the identification of active molecules, their reshaping by means of pharmaco-chemical drug design, and the creation of extremely efficacious and successful medicines, the pharmaceutical world sought a new source of inspiration. Such biota as the tropical forest, a quantity of plants credi...

6th century BCE, probably as part of the expansion into the region of the Persian Achaemenid Empire. Lying on one of the main branches of the ancient Silk Roads, which connected Europe and Africa to the Far East, a succession of cities flourished. By the early medieval period these encompassed over 1,000ha (Fig. 1). The great Islamic city of Sultan Kala, capital of the eastern Islamic world, wa...
Using established criteria for work with fossil DNA we have analysed mitochondrial DNA from 92 individuals from 18 locations in Denmark ranging in time from the Mesolithic to the Medieval Age. Unequivocal assignment of mtDNA haplotypes was possible for 56 of the ancient individuals; however, the success rate varied substantially between sites; the highest rates were obtained with untouched, fre...
