"There is in the world no rock
or tower of such height that
it cannot be scaled by any man
( provided he lack not feet)
if ladders are placed in the
proper position or steps are
cut in the rock, made in the right
place and furnished with railings
against the danger of falling over."

John Amos Comenius
