Not a 'Brief Guide' at all.  This book is, in fact, a large format paperback with many lavish colour plates of Cycladic figurines, pottery, clay seals, painted vases, jewellery and wall paintings from the heyday of the culture that ended with the volcanic eruption in C17th BC.  Following their recovery over many years of careful excavation these objects are now housed in the modern museum on the island of Santorini (Thera).  Paperback.  80 pages.  Bibliography.  Text in English and Greek.  Near new condition.  Cat No 3042
