frame was by no less a figure than Giuliano da Sangallo, who was just becoming Lorenzo il Magnifico's favourite architect. An enthroned Madonna and (rather large) Child sit on an elaborately-carved raised stone bench in a garden, with plants and flowers behind them closing off all but small patches of sky, to give a version of the hortus conclusus or closed garden, a very traditional setting for the Virgin Mary. Saints John the Baptist and an unusually elderly John the Evangelist stand in the foreground. Small and inconspicuous banderoles or ribbons carrying biblical verses elucidate the rather complex theological meaning of the work, for which Botticelli must have had a clerical advisor, but do not intrude on a simpler appreciation of the painting and its lovingly detailed rendering, which Vasari praised. It is somewhat typical of Botticelli's relaxed approach to strict perspective that the top ledge of the bench is seen from above, but the vases with lilies on it from below. The donor, from the leading Bardi family, had returned to Florence from over twenty years as a banker and wool merchant in London, where he was known as "John de Barde", and aspects of the painting may reflect north European and even English art and popular devotional trends. There may have been other panels in the altarpiece, which are now missing. San Barnaba Altarpiece A larger and more crowded altarpiece is the San Barnaba Altarpiece of about 1487, now in the Uffizi, where elements of Botticelli's emotional late style begin to appear. Here the setting is a palatial heavenly interior in the latest style, showing Botticelli taking a new degree of interest in architecture, possibly influenced by Sangallo. The Virgin and Child are raised high on a throne, at the same level as four angels carrying the Instruments of the Passion. Six saints stand in line below the throne. Several figures have rather large heads, and the infant Jesus is again very large. While the faces of the Virgin, child and angels have the linear beauty of his tondos, the saints are given varied and intense expressions. Four small and rather simple predella panels survive; there were probably originally seven. Other works With the phase of painting large secular works probably over by the late 1480s, Botticelli painted several altarpieces, and this appears to have been a peak period for his workshop's production of Madonnas.
