In this handout photo released by the Greek Culture Ministry on Wednesday, Aug. 20, 2014, front paw of a large stone sphinx is seen topping the entrance to an ancient tomb under excavation at Amphipolis in northern Greece. Archaeologists excavating the large grave mound on Thursday asked politicians and others seeking guided tours of the site to leave them in peace until the dig is completed. The partially uncovered tomb, from the end of Greek warrior-king Alexander the Great's reign, has captivated the public imagination, fueling wild speculation that it may contain rich treasure and the bones of an ancient celebrity.
