Now, as died the fulgurant rage that had supported her, and her normal strength being exhausted, a sudden weakness intervened, and she couldn't but allow Mike to lead her to a seat.
-- George Moore, Mike Fletcher: A Novel
He failed: the storm ran closer, fulgurant brilliance striding the sorry landscape like the stilted legs of some vast insect, the wind strengthening, carrying the odor of corruption, the thunder growling as if in anticipation.
-- Angus Wells, Wild Magic
Fulgurant is derived from the Latin word fulgurāre which meant "to flash like lightning."
