Apparently Muslims have a similar problem when determining which way to 
pray towards Mecca (Qibla).

This non-scientific website gives  a choice of 2 different directions:

There is more confusion found in the comments at the bottom of that website.

Ancient Astronomy and Astrology in Early Judaism

2015-09-24 Thread Dan-George Uza
Hello,

This might be of interest to researchers. "Zodiac Calendars in the Dead Sea
Scrolls and Their Reception - Ancient Astronomy and Astrology in Early
Judaism" by Helen Jacobus is a recent scholarly book (2014) about ancient
middle-eastern astronomy which also handles the subject of Greco-Roman
zodiac sundials in chapter 4. The entire work seems very well documented.

You can search for it on Scribd.com

​Regards,​

​Dan Uza

Well, if you are going to allow compass directions, then that opens the
door to all loxodromes.  There are an infnite number of loxodromes that
connect two points on a sphere, if you allow loxodrome paths that travel
more than once around the globe!  This gives an infinite number of compass
directions to Mecca.

I think you can face Mecca from 4 directions:

1. along great circle shortest direction
2. along great circle longest direction
3. along constant compass method shortest direction
4. along constant compass method longest direction

I wonder if it says in Koran to face Mecca in shortest direction?

Why not?  Richard Feynman argued that that a quantum mechanical particle can
take an infinite number of paths between two points to explain the wave
function.  Or something like that.  I don’t actually understand that stuff
myself. Maybe the direction to Mecca should be a wave function.

as a student of world war II methods of navigation, what about "pressure

Just thought I would confuse the issue.
