Perhaps this is obvious, but it had never occurred to me in any conscious way, and I wonder how far it is true, as I have a romantic image of people navigating by the stars. 

Will think about this today when we are travelling to Brazil on a night flight.  Will think of those daytime travellers and those starlight navigators.     

Safe travels, day or night. 

For ancient travellers travelled only by day.
