Constantin ROMAN bought his first prints whilst a postgraduate student in Cambridge, in the early 1970s, when very few people were interested in the subject and prices were accessible. Over the following thirty years, as a Geophysicist, he had the opportunity to travel extensively and added substantially to his collection, mostly from dealers in England, France and Holland. His particular interest concentrated on images from the Ottoman Empire in Europe, with emphasis on Wallachia and Moldavia (the Lower Danube and the Carpathians) as well as the Eastern part of the Habsburg Empire, (the Principality of Transylvania). Auxiliary themes of a wider regional interest (Polish, Russian, Balkan, Hungarian, Austrian, Turkish) are also present.
The subject of the collection has a strong topographical interest. It consists of maps (including plans of battles and strategic fortifications), views (landscapes and townscapes), costumes, portraits of historical characters, scenes of social and political interest, architectural / natural monuments, political cartoons of the 19th century, etc.
