Blake detested Newton, and his painting is, I believe, a gentle but forceful caricature wherein godlike man, dividers in hand, myopically fixes his gaze downwards on his own arid squiggles instead of raising his vision to behold the divinely created and spiritual, ie real, world. The effect of caricature will be emphasised, apparently, in the proposed sculpture by the substitution of a miniscule pyramid for Blake's dividers.
Blake's strongly held view of a certain kind of 'scientific' monocular vision is summed up in his famous lines (22 November 1802) to his patron, Sir Thomas Butts:
May God us keep
From single vision and Newton's sleep]
