Bianco di Santi alias Bianco da Siena or Bianco da Lanciolina was an Italian mystic poet and an imitator of Jacopone da Todi. He wrote several religiously-inspired poems. First a wool carder, he became a member of the poor Jesuates, founded by Giovanni Colombini. According to Feo Belcari, Bianco da Siena was native of Lanciolina di Valdarno, but he worked as a wool carder at Siena, his date of birth is uncertain, but took place around 1350, since Belcari defines him as young in 1367, when he entered the Jesuates. This company was founded towards 1360 by Colombini and his friend Francesco Vincenti: they proposed a life of poverty and penitence. In May 1367, Bianco da Siena entered the company and left Siena with them to ask the approval of Pope Urban V; the Jesuates were received with benevolence at Viterbo, where the pontiff stayed with the project to bring the Holy See to Rome. In the meantime, they were suspected of heresy: Colombini assuaged these suspicions, several members left the company.
During the return to Siena, Colombini fell ill and died at Acquapendente 31 July 1367. Because of the intervention of the Roman Curia, the Jesuates became a religious order: the members had to give up their roaming life and settled in Tuscany and in Umbria. Bianco da Siena stayed some time in Siena went to Città di Castello, which he left before 1383. Afterwards, he travelled with a colleague in Umbria and in Tuscany and he stopped in Pistoia, he settled in Venice, where he died in 1399. Bianco da Siena wrote several religiously-inspired poems; these were read in the Middle Ages and they are in many manuscripts. One hundred and twenty-two poems were published. Richard Frederick Littledale translated multiple poems into English that have come into common use in the Church.
