Oath Skull German. Probably 16th 17th century. Human skull,Sator formula in the letter square .
The effect of the Sator formula is unknown. There are numerous attempts at interpretation, including the arrangement of the letters in a double pater noster in the form of a cross around the fulcrum “N” and the remaining “A” and “O” (alpha-omega).
“The farmer Arepo has [as] works wheels’; that is, the farmer uses his plough as his form of work.” An alternative would be to interpret opera as the ablative instead of the nominative. In that case, the sentence could be read as ‘The farmer Arepo holds the wheels with difficulty (or with effort)’, shifting to focus on rotas with all its mystical connotations
