In Mercury, who is touching the trees with his caduceus and bidding them burgeon, some see Giuliano de' Medici, who was not yet betrothed. But when the picture was painted both Giuliano and Simonetta were dead: Simonetta first, of consumption, in 1476, and Giuliano, by stabbing in 1478. Lorenzo, who was at Pisa during Simonetta's illness, detailed his own physician for her care. On hearing of her death he walked out into the night and noticed for the first time a brilliant star. "See," he said, "either the soul of that most gentle lady hath been transferred into that new star or else hath it been joined together thereunto." Of Giuliano's end we have read in Chapter II, and it was Botticelli, whose destinies were so closely bound up with the Medici, who was commissioned to paint portraits of the murderous Pazzi to be displayed outside the Palazzo Vecchio. A third picture in what may be called the tournament period is found by some in the "Venus and Mars," No. 915, in our National Gallery. Here Giuliano would be Mars, and Venus either one woman in particular whom Florence wished him to marry, or all women, typified by one, trying to lure him from other pre-occupations, such as hunting. To make her Simonetta is to go too far; for she is not like the Simonetta of the other pictures, and Simonetta was but recently married and a very model of fair repute. In No. 916 in the National Gallery is a "Venus with Cupids" (which might be by Botticelli and might be by that interesting painter of whom Mr. Berenson has written so attractively as Amico di Sandro), in which Politian's description of Venus, in his poem, is again closely followed. After the tournament pictures we come in Botticelli's career to the Sixtine Chapel frescoes, and on his return to Florence to other frescoes, including that lovely one at the Villa Lemmi (then the Villa Tornabuoni) which is now on the staircase of the Louvre. These are followed by at least two more Medici pictures--the portrait of Piero di Lorenzo de' Medici, in this room, No. 1154, the sad-faced youth with the medal; and the "Pallas and the Centaur" at the Pitti, an historical record of Lorenzo's success as a diplomatist when he went to Naples in 1480.
