the San Marco Altarpiece (378 x 258 cm, Uffizi), is the only one to remain with its full predella, of five panels. In the air above four saints, the Coronation of the Virgin is taking place in a heavenly zone of gold and bright colours that recall his earlier works, with encircling angels dancing and throwing flowers. In contrast, the Cestello Annunciation (1489–90, Uffizi) forms a natural grouping with other late paintings, especially two of the Lamentation of Christ that share its sombre background colouring, and the rather exaggerated expressiveness of the bending poses of the figures. It does have an unusually detailed landscape, still in dark colours, seen through the window, which seems to draw on north European models, perhaps from prints. Of the two Lamentations, one is in an unusual vertical format, because, like his 1474 Saint Sebastian, it was painted for the side of a pillar in the Church of Santa Maria Maggiore, Florence; it is now in Milan. The other, horizontal, one was painted for a chapel on the corner of Botticelli's street; it is now in Munich. In both the crowded, intertwined figures around the dead Christ take up nearly all the picture space, with only bare rock behind. The Virgin has swooned, and the other figures form a scrum to support her and Christ. The Munich painting has three less involved saints with attributes (somewhat oddly including Saint Peter, usually regarded as in Jerusalem on the day, but not present at this scene), and gives the figures (except Christ) flat halos shown in perspective, which from now on Botticelli often uses. Both probably date from 1490 to 1495. Early records mentioned, without describing it, an altarpiece by Botticelli for the Convertite, an institution for ex-prostitutes, and various surviving unprovenanced works were proposed as candidates. It is now generally accepted that a painting in the Courtauld Gallery in London is the Pala delle Convertite, dating to about 1491–93. Its subject, unusual for an altarpiece, is the Holy Trinity, with Christ on the cross, supported from behind by God the Father. Angels surround the Trinity, which is flanked by two saints, with Tobias and the Angel on a far smaller scale right in the foreground. This was probably a votive addition, perhaps requested by the original donor. The four predella scenes, showing the life of Mary Magdalen, then taken as a reformed prostitute herself, are in
