Michelangelo's best work is only for two special family members.
Michelangelo's greatest work here is reserved for two minor members of the family, Lorenzo's grandson, Lorenzo the Duke of Urbino, portrayed as a pensive Roman soldier above two allegorical figures of Dawn (female) and Dusk (male), and his son, Giuliano the Duke of Nemours, more warrior-like above figures of Night (female) and Day (male).
