Dome - General Types - Umbrella Dome

Umbrella Dome

Also called pumpkin, melon, scalloped, or parachute domes, these are a type of dome segmented by ribs radiating from the center of the dome to the base. The material between the ribs arches from one to the other, transferring the downward force to them. The central dome of the Hagia Sophia uses this method, allowing a ring of windows to be placed between the ribs at the base of the dome. The central dome of St. Peter's Basilica also uses this method.

Famous quotes containing the words dome and/or umbrella:

    A starlit or a moonlit dome disdains
    All that man is,
    All mere complexities,
    The fury and the mire of human veins.
    William Butler Yeats (1865–1939)

    There are certain things—as, a spider, a ghost,
    The income-tax, gout, an umbrella for three—
    That I hate, but the thing that I hate the most
    Is a thing they call the Sea.
    Lewis Carroll [Charles Lutwidge Dodgson] (1832–1898)
