	Though a nun, Marianna was both rich and powerful: from a wealthy family, she also administered property revenues in Monza and was involved in administering justice. She started to exchange letters with Osio, delivered to his garden through a rope lowered from a window. The liaison was facilitated by the use of counterfeit keys provided by a blacksmith. The meetings between them were frequent and were organized with the complicity of other nuns and a priest named Paolo Arrigone, a close friend of Osio.
