Jeanette Winterson said this quote

That night two lovers whispering under the lead canopy of the church were killed by their own passion. Their effusion of words, unable to escape through the Saturnian discipline of lead, so filled the spaces of the loft that the air was all driven away. The lovers suffocated, but when the sacristan opened the tiny door the words tumbled him over in their desire to be free, and were seen flying across the city in the shape of doves.
