Screwdriver in the shop

Looking for Websites which may support our petition I came across a lot of superficial statements about Maria Valtorta, from people, who haven't really read the POEM, have not read the quaderni, don't know about the wondrous development and timing of the dictations and visions. That's a pity.
They get stuck with the screwdriver in Joseph's shop, mentionend in the POEM, and state that screws were invented centuries much later. 
This seems be a good test for the seriousness of the POEM.
Some <friends> of Maria Valtorta in these forums apologize for Maria Valtorta, that she was a simple women and couldn't differentiate the different tools...
Maria Valtorta doesn't need the apologizing and she wasn't a dumb women, she was well educated and had an extraordinary precise perception.
You probably know the Research paper of David J. Webster, where he states:
<The Pythagorean philosopher Archytas of Tarentum (5th century BC) is the alleged inventor of the screw. Screws came into common use around the 1st century BC. These were the wooden screws that were used in wine presses, olive oil presses and for

pressing clothes.>
