It is always better to have a reasonable sense of where you are. We find it helpful and reassuring to be able to plot where we have come from, where we are headed, and where we are at now.

To assist us, we make use of reference points that are stable, that we can take comparative readings from.

For the ancient traveler, the celestial bodies (sun, moon and stars) were those unmovable markers - set in their courses in the heavens above.

Should the unthinkable occur... should those markers fall...

How would the ancient traveler know where they were or which way to go on?

Are there any clearer, more permanent reference points by which a person might get their bearings?
