Original: Based on a suggestive phrase in a 1559 madrigal dedicated to Margaret of Parma, the illegitimate daughter of Holy Roman Emperor Charles V, which implied a long association with her, he may have accompanied her when she went to Naples in 1533, prior to marrying into the Medici family.
Simplified: Margaret, who was an illegitimate daughter of Charles V, was very wealthy and she married into the Medici family.
