Additional Discoveries of Aboriginal Rock Carvings in Tasmania

After several visits to the area rock workings were found on the southern slope of a high dolerite ridge known locally as "Billy Blue". They were ona large sand-stone rock measuring approximately sixty yards long and four yards wide. It faced west and was on the eastern bank of a creek bed which, though normally dry, has a permanent soakage at its mouth some fifty yards below the carved rock. A...

A CAD Paradigm to Produce Zillij Style of Geometrical Patterns for Wooden Carvings

This work presents a CAD paradigm to produce traditional zillij style of geometrical patterns using ubiquitous polygonal technique. This method makes use of a grid generated from diagonals of n-sided regular polygon. The grids are in the form of a mesh of having large number of irregular polygons. The vertex of any irregular polygon in the grid is viewed as the point of intersection of two diag...

Observations on Some Rock Carvings of Surgical Instruments in East Africa

have no knowledge whatever of archaeology, mineralogy, etc., the essentials for the serious study of the subject. When I finally did visit Africa, my interests were botanical with a strong surgical bias, as I had intended to specialize in surgery when I studied medicine nearly 50 years ago. As soon as the opportunity offered itself I visited the Great Zimbabwe3 and I shall always remember the a...

Dating study of two rock crystal carvings by surface microtopography and by ion beam analyses of hydrogen

Two artefacts made of rock crystal (quartz) from the collection of the Musée du quai Branly in Paris, France, a skull approximately half of the size of a real cranium and a smaller anthropomorphic head, purportedly attributed to pre-Columbian Mesoamerican cultures, were studied to assess their authenticity. The surface of the artefacts were examined by means of optical microscopy and scanning e...
