Niccolò Ricciolini was an Italian painter, etcher and architect. He trained in his father's workshop. In 1721, he became a member of the Accademia di San Luca. His first independent commission was an altarpiece for the chapel of a villa in Frascati in 1709. Between 1713 and 1715, Ricciolini travelled several times to Macerata to work on a fresco project of his father and to fresco a chapel on his own. After his father's death in 1715, Ricciolini completed several of his father's projects around Rome. From 1718 to 1736, he collaborated on the construction of St. Peter's Basilica: he designed some cartoons for mosaics and restored paintings. Ricciolini specialised in religious and history paintings. Although he was considered a rather mediocre painter throughout his life, he had a great talent for adapting and uniting the most important stylistic trends of his time. He was also active as an architect.
