It would seem funny to me to have two of the same symbols (a snake)represented on the same card - the serpent eating its tail, (the belt of the Magician) and then the snake (straight) on the table - unless there is a corelation between the two (and I dont see the straight snake being opposite to the round snake) - but then again - would there be something in that?
It would be more likely to see the snake represented in the tree - or in the lemniscate.
Just some thoughts.
