Gratillonius On Hadrian's Wall

At present, I am more interested in Gratillonius of the Roman Empire than in Wing Alak of the Galactic League. On the opening page of Roma Mater, Gaius Valerius Gratillonius, a Romano-Briton and Roman centurion, standing on Hadrian's Wall, fifteen feet high and seventy-seven miles long, at noon on the Birthday of Mithras, sees: 

clear sky;

low blazing sun;

southward, hills, ditch, earthworks, fields, fort and settlement;

northward, the Wall's shadow on a descending cliff, forested heights, flashing icicles and flying crows;

westward, a nearby tower;

eastward, the Wall stretching over the horizon with observation turrets, mile-castles, gleaming metal, cloaks and standards and, below it, the legionary base.

And that is a good start to a historical Tetralogy.
