“For what is orientation, or direction? What is the meaning of North, South, East or West?
How did we derive these fixed points to start with? Not from any local or national origin;
for pure direction is entirely independent of locality. It is, in fact, derived solely from the movements
of the ‘heavens’. It is only by reference to the position of the stars, sun or moon that azimuth,
or true direction, exists. There is no other meaning in the term.”
– H. Boyle Somerville (1912)
