Emanuel Sweert (1552–1612) was a Dutch painter and nurseryman noted for his publication in 1612 at Frankfurt-am-Main of Florilegium Amplissimum et Selectissimum. Sweert was born at Zevenbergen and lived in a period when new plants from across the world were being introduced to Europe via Dutch, English and French ships. To meet the burgeoning interest in plants by the public, nurseries were being established by wealthy merchants in order to meet the demand. Botanical illustration suddenly found a new outlet in the production of nursery catalogues. Sweert prepared his Florilegium as a guide of his available stock for the Frankfurt Fair of 1612. The plates, depicting some 560 bulbs and flowers, were from the Johann Theodore de Bry Florilegium which in turn was based on that by Pierre Vallet.
