Many projects listed below were made possible and supported by colleagues and several institutions. I am especially obliged to my friend Donato Attanasio from the CNR in Rome and Dr. Sabine Ladstätter, director of the Austrian Archaeological Institute (ÖAI - www.oeai.at) for many years of proliferous cooperation.
