The treasure rooms of Naturalis Biodiversity Center and the Leiden University Library contain magnificent old books and herbaria with dried plant specimens, botanical drawings, and thousands of glass jars with roots, seeds and barks, collected from the 16th to the 19th century.
Our major study objects are:
The herbaria of Leonhard Rauwolf (1560-1576), collected in southern France, Italy, Lebanon, Syria and Iraq. This early German explorer travelled to the Near East in search for herbal medicine. Risking his own life but driven by curiosity, Rauwolf documented useful plants among Arabs, Turks, Kurds and Jews in Aleppo, Mosul, Baghdad and Tripoli.
Icones Plantarum Malabaricarum
18th century botanical drawings from Sri Lanka. An unknown VOC doctor made 262 watercolour drawings of medicinal plants and recorded the recipes from traditional healers and local people around 1700 in the Dutch colony Ceylon.
The En Tibi herbarium
One of the oldest herbaria in the world (ca. 1555), made by an unknown Italian botanist, containing almost 500 specimens, including the oldest tomato and hot pepper from the recently discovered American continent.
Herbaria Simone D’Oignies
A mysterious army surgeon collected six volumes of plant specimens around 1780. The origin of the collections in unknown, but point towards botanical gardens in the Netherlands and Belgium.
Hundreds of small glass jars with medicinal barks, roots and seeds from China are kept in museums and private collections throughout the Netherlands. They reflect centuries of trade in Chinese herbal medicine. What species are involved? Do these medicines still contain active properties after all these years?
