He was born in Florence, on his mother's side the grandson of a painter. Although he was precocious and apprenticed at a young age to Jacopo Vignali, Dolci was not prolific. "He would take weeks over a single foot", according to his biographer Baldinucci. His painstaking technique made him unsuited for large-scale fresco painting. He painted chiefly sacred subjects, and his works are generally small in scale, although he made a few life-size pictures. He often repeated the same composition in several versions, and his daughter, Agnese Dolci, also made excellent copies of his works. Dolci was known for his piety. It is said that every year during Passion Week he painted a half-figure of the Savior wearing the Crown of Thorns. In 1682, when he saw Giordano, nicknamed "fa presto", paint more in five hours than he could have completed in months, he fell into a depression. Dolci's daughter, Agnese, was also a painter. Dolci died in Florence in 1686.
Works
The grand manner, vigorous coloration or luminosity, and dynamic emotion of the Bolognese-Roman Baroque are foreign to Dolci and to Baroque Florence. While he fits into a long tradition of prestigious official Florentine painting, Dolci appears constitutionally blind to the new aesthetic, shackled by the Florentine tradition that holds each drawn figure under a microscope of academicism. Wittkower describes him as the Florentine counterpart, in terms of devotional imagery, of the Roman Sassoferrato. Pilkington declared his touch "inexpressibly neat... though he has often been censured for the excessive labour bestowed on his pictures, and for giving his carnations more of the appearance of ivory than the look of flesh", a flaw that had been already apparent in Agnolo Bronzino. Among his best works are a St Sebastian; the Four Evangelists at Florence; Christ Breaking the Bread; the :Image:Dolci Cecilia organo.jpg|St Ceciliaat the Organ; an Adoration of the Magi in the National Gallery, London; the :Image:Dolci Caterina leggente.jpg|St Catherine Reading and St Andrew praying before his Crucifixion in the Palazzo Pitti. He completed his portrait of , when he was only sixteen. He also painted a large altarpiece for the church of Sant' Andrea Cennano in Montevarchi. As was typical for Florentine painters, this was a painting about painting, and in it the Virgin of Soriano holds a miraculous and iconic painting of St Dominic.
