This collection brings together art historians, museum professionals, conservators, and conservation scientists whose work involves Rembrandt van Rijn and associated artists such as Gerrit Dou, Jan Lievens, and Ferdinand Bol. The range of subjects considered is wide: from the presentation of convincing evidence that Rembrandt and his contemporary Frans Hals rubbed elbows in the Amsterdam workshop of Hendrick Uylenburgh to critical reassessments of the role of printmaking in Rembrandt’s studio, his competition with Lievens as a landscape painter, his reputation as a collector, and much more. Developed from a series of international conferences devoted to charting new directions in Rembrandt research, these essays illuminate the current state of Rembrandt studies and suggest avenues for future inquiry.
