Francesco degli Organi, Francesco il Cieco, or Francesco da Firenze, called by later generations Francesco Landini or Landino (c. 1325 or 1335 – September 2, 1397) was an Italian composer, organist, singer, poet and instrument maker. He was one of the most famous and revered composers of the second half of the 14th century, and by far the most famous composer in Italy.
Details of Landini's life are sketchy and few facts can be established with certainty, but the general outline has begun to take shape as more research has been done, especially into Florentine records. Most of the original biographical data on him comes from a 1385 book on famous Florentine citizens by chronicler Filippo Villani, who was also born approximately 1325.
Landini was most likely born in Florence, though his great-nephew, humanist Cristoforo Landino, gave his birthplace as Fiesole. His father, Jacopo del Casentino, was a noted painter in the school of Giotto. Blind from childhood (an effect of contracting smallpox), Landini became devoted to music early in life, and mastered many instruments, including the lute, as well as the art of singing, writing poetry, and composition. Villani, in his chronicle, also stated that Landini was an inventor of instruments, including a stringed instrument called the 'syrena syrenarum', that combined features of the lute and psaltery, and it is believed to be the ancestor of the bandura.
