Jacob Marrel (1614-1681) was a draftsman and painter, born in Frankfurt am Main, where he worked during a large part of his life. One of his works was a book with images of tulips supplemented with insects and flowers, graphite, watercolor and gouache on mainly white parchment, 339 x 450 mm. Formerly owned by E.H. Krelage in Haarlem, sold in 1965 (probably already incomplete) after his death in 1956 by his wife Elizabeth Keppel Hesselink to the Parisian art dealer Anne Otto Wertheimer; then the remainder was dispersed. Some leaves were auctioned in 1982 as part of her estate. At present a number of sheets are known, including Rijksprentenkabinet Amsterdam, The Metropolitan Museum of Art (New York), Teyler Museum (Haarlem) and in private collections in New York and Boston. The total number of pages is unknown, but must have had at least 29 as a leaf in Boston carries this number. It is likely that this work originated during his Utrecht period (1632-1650). 
Todays drawing is in the collection of Teylers Museum . It is entitled Three tulips with insects. Only after zooming in one sees a snail on the stem of the tulip at left. It is somewhat stylized specimen, with a brownish dextral shell and a grayish animal. It represents an (as yet) unidentifiable species.
