from a repast, testifying to a more than ordinary farewell. Stelae surmounted the mounds. A walled enclosure, Grave Circle A, included six more shaft graves, with nine female, eight male, and two juvenile interments. Grave goods were more costly than in Circle B. The presence of engraved and inlaid swords and daggers, with spear points and arrowheads, leave little doubt that warrior chieftains and their families were buried here. Some art objects obtained from the graves are the Silver Siege Rhyton, the Mask of Agamemnon, the Cup of Nestor, and weapons both votive and practical. The chemical compositions of the silver objects indicate that the silver was sourced from several locations. Late Helladic II (LHII; c. 1450–c. 1400 BC) Alan Wace divided the nine tholos tombs of Mycenae into three groups of three, each based on architecture. His earliest – the Cyclopean Tomb, Epano Phournos, and the Tomb of Aegisthus – are dated to LHIIA. Burial in tholoi is seen as replacing burial in shaft graves. The care taken to preserve the shaft graves testifies that they were by then part of the royal heritage, the tombs of the ancestral heroes. Being more visible, the tholoi all had been plundered either in antiquity, or in later historic times. Late Helladic III (LHIII; c. 1400–c. 1050 BC) At a conventional date of 1350 BC, the fortifications on the acropolis, and other surrounding hills, were rebuilt in a style known as Cyclopean because the blocks of stone used were so massive that they were thought in later ages to be the work of the one-eyed giants known as the Cyclopes. Within these walls, much of which can still be seen, successive monumental palaces were built. The final palace, remains of which are currently visible on the acropolis of Mycenae, dates to the start of LHIIIA:2. Earlier palaces must have existed, but they had been cleared away or built over. The construction of palaces at that time with a similar architecture was general throughout southern Greece. They all featured a megaron, or throne room, with a raised central hearth under an opening in the roof, which was supported by four columns in a square around the hearth. A throne was placed against the center of a wall to the side of the hearth, allowing an unobstructed view of the ruler from the entrance. Frescos adorned the plaster walls and floor. The room was
