The problem I have with alignment stories is they never say what the alignment is, or rather, they assume that the earth is flat, so that map line=great circle=sunrise alignment

If they drew this with a ruler on a map, were they aware that the map is a conic projection? Are they actually drawing a great circle, or a line of constant sunrise alignment? (it can't be both, and the constant alignment would only look straight on a Mercator map, which single-country maps rarely are)

Also, why don't they show all the St. Michaels nearby that aren't on the line? There could be hundreds of them.
