 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.From 1408 to 1418, Fra Angelico was at the Dominican friary of Cortona, where he painted frescoes, now mostly destroyed, in the Dominican Church and may have been assistant to Gherardo Starnina or a follower of his.Between 1418 and 1436 he was at the convent of Fiesole, where he also executed a number of frescoes for the church and the Altarpiece, which was deteriorated but has since been restored.
