De Witt offers a detailed biography based on a thorough review of the documentary evidence. He traces Van Noordt's origins back to a prominent musical family, details his artistic development under the guidance of prominent Amsterdam painter Jacob Adriaensz Backer, and reveals his synthesis of the styles of the two dominant Netherlandish artists, Rubens and Rembrandt. Using a systematic analysis of technique, manner, and approach to form, de Witt proves that over half the paintings and drawings presently attributed to Van Noordt are not his work - virtually recasting the accomplishments of an artist whose vibrant, often daring works challenge our concept of seventeenth-century Dutch art.

The art of the Netherlands (Dutch and Flemish) is unique in Early Modern Europe in its concern for military cruelty against civilians, principally the peasantry. Decimated by time and changes in taste, this popular iconography proves varied and extensive, stretching from Bruegel to and past Rubens. 'Massacres of the Innocents' continue to be a favourite subject through the Eighty Years War, in contrast to ruling-class glorifications of war. Dutch patriotic siege prints lay claim to 'scientific' precision in landscapes free of military terror, while the idea of military conquest is presented as generous rather than cruel in the ever-popular figure of Scipio Africanus. Most of the pictorial material is unfamiliar, some of it even to specialists and never before published; new light is shed on the more familiar phenomena of the civic guard groups and Ter Borch courtier-officers, 'good soldiers' overcoming a bad image.
