How many names can one goddess have? Leaf and Bayfield say that Atrutônê may mean Tireless or Unwearied from τρυω to rub but it cannot be said with confidence it is of Hellenic origin at all. Or it may be connected with the first element in Tritogeneia
Most Impressive.
We have to consider these were all different Athenas altogether. They were seen as individual manifestations of the goddess representative of local beliefs, not variations on the same goddess that somehow disagreed. In other words, each name represents what each city believed was Athena.
