There are no builders like the Dwarves, and this is their greatest ancestral
home. Why shouldn't it be glorious! Think of the great Cathedrals and stately
homes of Europe--their ceilings soar as well. A general rule in most
architechture seems to be the grander the space, the higher the ceiling.
Dwarrowdelf was built to impress any visitors with the skill of the makers.
I rather doubt that mining was behind it. The evenly spaced columns suggest
that beauty and symmetry were foremost in the minds of the designers. It's not
too likely that the mithril veins were found only in the open spaces. That
would stretch credibilty too far,
IMO.
"...their hearts, wounded with sweet words, overflowed, and their joy was like swords, and they passed in thought out to regions where pain and delight flow together and tears are the very wine of blessedness."
