“begotten after a certain manner with man”
The God under whose protection each man lives when he is born is called genius.
This Latin definition is one of the most repeated in the twelfth century in relation to genius.
Its in this area, the relationship with fate and skill that genius seems somewhat fishy.
It’s tempting to speculate that Genius may not be a complete Latin borrowing, but may have attached and become entwined with existing concepts already live in the population relating to craft activities and chance.
Its meeting once more a part of where it came from as it moves from classical text into medieval culture.
Its not a movement into an empty cultural space.
