Not P but Moby-Dick (24)

[Mike Jing]

>From Chapter 41:

Winding far down from within the very heart of this spiked Hotel de Cluny
where we here stand—however grand and wonderful, now quit it;—and take your
way, ye nobler, sadder souls, to those vast Roman halls of Thermes; where
far beneath the fantastic towers of man’s upper earth, his root of
grandeur, his whole awful essence sits in bearded state; an antique buried
beneath antiquities, and throned on torsoes!

What does "bearded" mean here? Is it just the usual meaning, or is it
something else?
