art works it was viewed by more than a million people. His only large painting with a mythological subject ever to be sold on the open market is the Venus and Mars, bought at Christie's by the National Gallery for a rather modest £1,050 in 1874. The rare 21st-century auction results include in 2013 the Rockefeller Madonna, sold at Christie's for US$10.4 million, and in 2021 the Portrait of a Young Man Holding a Roundel, sold at Sotheby's for US$92.2 million. The first nineteenth-century art historian to be enthusiastic about Botticelli's Sistine frescoes was Alexis-François Rio; Anna Brownell Jameson and Charles Eastlake were alerted to Botticelli as well, and works by his hand began to appear in German collections. The Pre-Raphaelite Brotherhood incorporated elements of his work into their own. Walter Pater created a literary picture of Botticelli, who was then taken up by the Aesthetic movement. The first monograph on the artist was published in 1893, the same year as Aby Warburg's seminal dissertation on the mythologies; then, between 1900 and 1920 more books were written on Botticelli than on any other painter. Herbert Horne's monograph in English from 1908 is still recognised as of exceptional quality and thoroughness, "one of the most stupendous achievements in Renaissance studies". Botticelli appears as a character, sometimes a main one, in numerous fictional depictions of 15th-century Florence in various media. He was portrayed by Sebastian de Souza in the second season of the TV series Medici: Masters of Florence. The main belt asteroid 29361 Botticelli discovered on 9 February 1996, is named after him.
