Mythological or literary boys names?

[GoldenRosebee]

I'm just a namenerd, but would like to think of names I could use in future. This is just for fun, tho.

What usable, but nice, boys names you can think of that are of mythology, medieval tales, astronomical or literature origin? Historic name are fine, as well as dated names.
These are names I already have on my list... what else can you add, I feel some of them aren't very usable.
Caspian
Dorian
Endymion
Florian
Gwydion
Lucius
Lysander
Oberon
Orpheus
Peredur
Arthur
August
Cedric
Dylan
Emil
Gareth
Gustav
Hermes
Percy
Roland
Samson
Sigurd
Thorin
Tristan

Gareth is one of my favourite names and is my favourite Knight of the Round Table!

So to add some others (they may be too out there, but I'll still list them:

Gawain (Arthurian)
Gaheris (Arthurian)
Kay (Arthurian)
Owain (Arthurian/Mabinogi)
Morgan (Arthurian) - Morgan is a female in the stories, but it's usually been used as a boy's name here.
