As a physician, Worth was clearly interested in the medicinal use of plants and he collected some of the finest herbals available: works by leading sixteenth-century botanists such as Otto Brunfels, Leonhard Fuchs, and Pietro Andrea Mattioli who had led the way in pictorial depiction of plants in the sixteenth century; treatises by Adam Lonicer and Konrad Gesner as well as texts by the late sixteenth-early seventeenth-century Dutch triumvirate of Rembert Dodoens, Matthias de L’Obel and Carolus Clusius. Alongside these were the huge botanical encyclopaedias of the seventeenth century by Jean Bauhin, John Parkinson and John Gerard.
