Usage examples of "archaicness".
The silence, the sputtering green candles, the heavy dark wood everywhere, the ponderous beams, which seemed to drip shadows, the roughness, indeed, the archaicness, of the room, and the corpse-like sleeper, who was so expected and yet so unexpected--these fell like heavy shrouds, one over the other, upon him.
