This library covers many areas and could be that of an educated Amsterdam merchant of the eighteenth century: it includes historical works, topography and travel journals, works about the natural sciences and a remarkable anthology of Dutch literature in which even the minor poets are well represented. Needless to say, works about the arts were Lugt’s major interest: early art history, artists’ biographies, essays on aesthetics, collection catalogues and every other conceivable art history source. The high quality of Netherlandish book illustration in the sixteenth and seventeenth centuries was another guideline in Lugt’s acquisition policy. This applies in particular to two kinds of illustrated works that are particularly well represented and actively pursued: emblemata literature and triumphalia. Seventeenth-century Netherlandish calligraphy forms a separate ensemble, with specimens by the renowned calligraphers of their day.
