By the following lines I should like to express my gratitude to Fritz Eichler, the late Director of the Austrian Archaeological Institute, a gentleman whose like may not be found so easily nowadays, who made possible A. Bammer's work at the Ephesus Artemisium, and who directed my interest to East Greek art and artistry as well, since at the moment times are hard for an archaeologist who works on other than Roman Imperial trifles at Efes City.
When Bammer came across bobbin-like objects made of rock crystal, some people thought that he had found parts of Wood's surveying devices or the like, in spite of the fact that they came without any doubt from stratified layers dated between 650 and 550 B.C. Besides, Hogarth had unearthed some 15 pieces of this type already. These “large studs or buttons”, as Hogarth had called them, are hyperboloids of specific shape turned on a lathe, as can be inferred by a faint deepening in the centre of the larger side of some of these hyperboloids. The larger side is always concave, the smaller one plane or slightly convex.
