Antonio Nicolotti

 was a member of one of the most prominent families in 16th century Venice, and the brother of Baldassare Nicolotti. After Baldassare was accidentally killed by Galileo Galilei, he sought revenge. When he met Steven Taylor, he mistook him for Galileo and tried to fight him. Christopher Marlowe (going by the name Giovanni Zarattino Chigi) intervened and saved Steven. (PROSE: The Empire of Glass)
