Objects which are usually the motives of our travels by land and by
sea are often overlooked and neglected if they lie under our eye....
We put off from time to time going and seeing what we know we have
an opportunity of seeing when we please.
-- Pliny the Younger (61-105 AD)
-- Letters, Book viii, Letter xx, 1
The world, and whatever that be which we call the heave by the
vault of which all things are enclosed, we must conceive to be a deity,
to be eternal, without bounds, neither created nor subject at any
time to destruction....
