This relates very nicely to my post on Steampunk Settings.
From Altas Obscura, a guide to the symbolism found in graveyards–apropos for Halloween.
Growing up near Boston, I sometimes wandered the burying grounds in Boston where the stones date back to the founding of Boston. Many of the colonial era graves have intricate carvings which are still crisp and sharp. Death, the winged skull, the winged hourglass (Tempus Fugit!) and the draped urn are all symbols of death that can be seen there.
And this was all before the excess decoration of the Victorian Era.
