This city names a style of chamber tomb cut into the bedrock of a hillside accessed through a narrow ditch in the ground. A golden dove cup and an electrum death mask named for a letter have been found outside this city’s citadel in the early (-5[1])style of shaft graves (15[1])of Grave Circles A and (15[1])B. A red marble structure traditionally (15[1])called a “treasury” in this (-5[1])city is the (-5[1])largest (-5[1])of its era’s corbelled beehive (-5[1])tombs. Along with (15[1])the (-5[1])nearby Tiryns, this city is the (15[1])most famous example of limestone (-5[1])(*) Cyclopean walls, which the Lion Gate permits entry (10[1])through. It’s (-5[1])not Troy, but Heinrich Schliemann arbitrarily called a gold (-5[2])artifact found in this city the Mask (-5[1])of Agamemnon. For 10 points, name this Bronze (10[1])Age city that names the earliest period of peninsular Greek civilization. (10[8]0[4])■END■
