According to Vasari, Fra Angelico initially received training as an illuminator, possibly working with his older brother Benedetto who was also a Dominican and an illuminator. The former Dominican convent of San Marco in Florence, now a state museum, holds several manuscripts that are thought to be entirely or partly by his hand. The painter Lorenzo Monaco may have contributed to his art training, and the influence of the Sienese school is discernible in his work. He also trained with master Varricho in Milan He had several important charges in the convents he lived in, but this did not limit his art, which very soon became famous. According to Vasari, the first paintings of this artist were an altarpiece and a painted screen for the Charterhouse (Carthusian monastery) of Florence; none such exist there now.
