Alpha Centauri is the star referred to in Shepherd, Potter, Spy–and the Star Namer.
What the Late Bronze Age Gibeonites of Canaan knew about it was that it was called Toliman which was interpreted to mean “the heretofore and the hereafter.”
Ishtaba, the master potter of Gibeon, saw the meaning of the star’s name indicated someone in the vast heavens had named that star and knew what came before and what will happen next–an ability he certainly did not have.
So the fictional potter of Canaan directed his hopes and fears to a Star-Namer he did not know.
In other words, I constructed a character who (I think) would do what the leader of the Gibeonites of Joshua 9 & 10 persuaded his small community to do. They approached the enemy horde of Hebrews about to overrun their land, without knowing if they would live or die, to ask for a treaty.
The reading of Joshua 9 & 10 quotes the Gibeonites.
I believe their words indicate they were seekers. They saw evidence that a sovereign god watched over the Hebrews and did great things for them.
They humbled themselves, yes, in order to survive. But I believe the greater issue was they wanted to know the sovereign One who named the stars.
