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.
Modern scholars no longer accept the idea that Landini was a member of the Landini family and prefer to use the names 'Francesco da Firenze' (Francesco of Firenze), 'Francesco degli Organi' or 'Francesco degliorghani' (Francesco of the organs) and 'Francesco il Cieco' or 'Franciscus cecus' (Francesco the blind) to refer to the composer. The reason is that the surname 'Landini' or 'Landino' has not been linked to the composer in any sources of the 14th century nor in secondary references in the 15th century. The evidence linking Francesco to the Landini family via his presumed father, who was identified by Filippo Villani as a painter who lived a simple life is no longer accepted by art historians. It can therefore also no longer be maintained that the painter Jacopo del Casentino (formerly also referred to as 'Jacopo Landino') was his father or that Cristoforo Landino was his great-nephew.
Landini was most likely born in Florence, though Cristoforo Landino, gave his birthplace as Fiesole. 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.
