"In Beleriand, King Thingol
upon his throne was as the lords of the Maiar whose power is at rest,
whose joy is as an air that they breathe in all their days,
whose thought flows in a tide untroubled from the heights to the deeps."
JRR Tolkien,
The Silmarillion
Thingol throned in his grand and secret underground kingdom
The pillars were said to be sculpted like great beech trees, with
golden lamps hung from all their branches.
In the frame, either side of him are symbols based on those for Melian
(his wife) and Luthien (his daughter),
and above him his doom: the 'Nauglamir' necklace with a Silmaril in the
middle.
