<HTML>OK, I've changed my mind... my opinion wrt the statement by RB in his rebuttal of Krupp is no longer that it was a mistake on RBs part.
Having re-read it I can confidently put it into context and see it for what it is.
Krupp accused RB of having Orion 'upside down'. RB countered this with his insistance that the AE's saw the sky differently (South is up) and that his theory is still valid. This is where the statement you posted comes in. RB is showing that by printing the map in question, Krupp is actually backing RBs statement that different people see the sky differently, in this case from outside the celestial sphere. Krupp presumably accepts that early modern astronomers depicted the heavens from this perspective, yet in his rebuttal of the OCT he does not even consider that the AEs looked at the sky in a different way than ourselves. The remark about the printers is sarcasm fuelled by the irony of the situation.
