Corona

The magnificent bronze corona, or luminaria, which still hangs in the central octagon, shews the skill of the workmen in bronze of that period.

The cornice only is carried around the room at the ceiling, and in the staircase hall only the cymatium and corona of the cornice; but over the archway, supported by a colonnade of four fluted round columns, a complete entablature with nicely worked classic detail is employed and given added emphasis by several inches' projection into the reception hall.

Though somewhat verbose, the author is specific in his instruction that the S-shaped crown molding, the cymarecta, caps the top of the pediment and is not returned on the horizontal corona.

My investigations seem to prove conclusively that the theoretical corona is caused by light emitted and reflected from streams of matter ejected from the Sun by forces which, in general, act along lines normal to the surface. These forces are most active near the center of each Sun-spot zone.

The corona is a high-temperature portion of the Sun's outer atmosphere, beginning slightly above the visible surface and extending hundreds of thousands of kilometers, or further, into interplanetary space.

The area density of impact craters on the surfaces of the coronas suggests that the episode of tidal heating occurred approximately one billion years ago[…].

It looked like a miniaturized version of Hiroshima. Fires burned here and there. […] His once and future presidential palace was a crater ringed by a corona of flaming debris.
