Not just talk: Sustainable therapeutic experiences are based on bodily experiences.

The first article in this volume presents 17 bronzes that came to light among the ruins of an enwalled settlement atop the Jabal al-‘Awd, a nearly 3000-meter high mountain located some 50 km east of Ibb. The figural bronzes encompass Egyptian or Greek-Roman kinds, but also those obviously produced in South Arabia that display the influence of works from the Mediterranean sphere. Residences of rulers and palaces are a well-known occurrence among ancient civilizations. This applies to ancient South Arabia as well, whence a number of such complexes are found, for example, the palace of Gumdan in Sana’a. The description of Gumdan, as documented by al-Hamdani for instance, shows great similarity with the rock paintings at Djarf al-Yahudi, a basolt promontory located ca. 50 km east of Sana’a. The second contribution in this tome provides a description of these rock paintings and compares them with the documentation made by al-Hamdani.

Composite materials are engineered materials, made from two or more constituents with significantly different physical or chemical properties which remain separate on a macroscopic level within the finished structure. Due to their special mechanical and physical properties they have the potential to replace conventional materials.
