Director of the Collection of Old Masters, Olga Kotková is a specialist in German, Austrian, and Netherlandish 15th and 16th century painting and sculpture; furthermore, she focuses on Rudolfine and 17th century Flemish painting. Dr Kotková concentrates on the relationship and art exchange between Netherladish and German art and the art produced in the Lands of the Bohemian Crown. These areas of interest led her to create many publications at home and abroad, dealing for example with the work of Lucas Cranach, Albrecht Dürer, and Roelandt Savery. Dr Kotková has also authored several catalogues raisonné of the National Gallery Prague: Netherlandish Painting 1480–1600, German and Austrian Painting of the 14th–16th Centuries, co-authoring the catalogue titled German, Austrian, French, Hungarian and Netherlandish Sculpture 1200–1550.
