the Philadelphia Museum of Art. After about 1493 or 1495 Botticelli seems to have painted no more large religious paintings, though production of Madonnas probably continued. The smaller narrative religious scenes of the last years are covered below. Madonnas, and tondos Paintings of the Madonna and Child, that is, the Virgin Mary and infant Jesus, were enormously popular in 15th-century Italy in a range of sizes and formats, from large altarpieces of the sacra conversazione type to small paintings for the home. They also often hung in offices, public buildings, shops and clerical institutions. These smaller paintings were a steady source of income for painters at all levels of quality, and many were probably produced for stock, without a specific commission. Botticelli painted Madonnas from the start of his career until at least the 1490s. He was one of the first painters to use the round tondo format, with the painted area typically some 115 to 145 cm across (about four to five feet). This format was more associated with paintings for palaces than churches, though they were large enough to be hung in churches, and some were later donated to them. Several Madonnas use this format, usually with a seated Virgin shown down to the knees, and though rectangular pictures of the Madonna outnumber them, Madonnas in tondo form are especially associated with Botticelli. He used the tondo format for other subjects, such as an early Adoration of the Magi in London, and was apparently more likely to paint a tondo Madonna himself, usually leaving rectangular ones to his workshop. Botticelli's Virgins are always beautiful, in the same idealized way as his mythological figures, and often richly dressed in contemporary style. Although Savonarola's main strictures were against secular art, he also complained of the paintings in Florentine churches that "You have made the Virgin appear dressed as a whore", which may have had an effect on Botticelli's style. They are often accompanied by equally beautiful angels, or an infant Saint John the Baptist (the patron saint of Florence). Some feature flowers, and none the detailed landscape backgrounds that other artists were developing. Many exist in several versions of varying quality, often with the elements other than the Virgin and Child different. Many of these were produced by Botticelli or, especially, his workshop, and others apparently by unconnected artists. When interest in Botticelli revived in the 19th century, it was
