It was Pietro Redondi who put forward the thesis that atomism was at the center of the Galileo Trial because of its inherent challenge to the Eucharist. As I said, it is a very controversial claim. It is known that Galileo got into trouble with the Jesuits over atomism before his trial.
Regarding suavity, Lucretius uses it in reference to 'sweet flowers'. tibi suavis daedala tellus summittit flores, tibi rident aequora ponti placatumque nitet diffuso lumine caelum. My rough translation: "For you the clever Earth sends forth sweet flowers, for you laugh the waves of the sea, and the calm sky shines with diffuse light."
