Denis[a] Calvaert (Dutch: [ˈdɛnɪs ˈkɑlvaːrt]; around 1540 – 16 April 1619) was an Antwerp-born Flemish painter who spent most of his life in Italy, where he was known as Dionisio Fiammingo[1] (Italian: [di.oˈniːzjo fjamˈmiŋɡo, djoˈ-]) or simply Il Fiammingo ("the Fleming").

Some of his best known works include his rendition of The Resurrection of Christ[2] and Saint John the Baptist in the Wilderness.

He took as a pupil the daughter of his mentor, Lavinia Fontana,[5] and a number of prominent young apprentices, including Guido Reni, Giovanni Battista Bertusio, Francesco Albani and Domenichino,[6] who soon followed Annibale Carracci's example and took prominent commissions in Rome.

[8] Calvaert typically used chiaroscuro techniques to set stylized foreground figures derived from Correggio against northern European landscapes.

While continuing to pursue a mannerist aesthetic throughout his career, Calvaert became a significant contributor the brand of classicism that came to characterize the Bolognese school of painting from the start of the 17th century.
