"There are more things in heaven and earth, Horatio, than are dreamt of in your philosophy."
-Hamlet, Act One, Scene Five
This above all: to thine ownself be true, And it must follow, as the night the day, Thou canst not then be false to any man.” - (again with the Hamlet)
One of our treats on the trip to Egypt was to sail in a felucca on the Nile.
This is across the harbour from Aswan. If you enlarge it you will see some feluccas on the right.
