Metamorphosis Insectorum Surinamensium

About this item

In 1699 Maria Sibylla Merian sailed from Amsterdam to the Dutch colony of Surinam, accompanied by her daughter Dorothea Maria, having partly funded the expedition by selling her own collections and paintings. She was 52. She spent roughly two years there collecting, rearing and painting insects before illness forced her home, and published the resulting plates in 1705 as Metamorphosis Insectorum Surinamensium, in Latin and Dutch editions.

What makes the book unusual for its period is the composition of the plates. The convention was to depict a specimen in isolation, as a dead object, arranged for comparison. Merian drew the insect on the plant it actually fed on, and she drew it at several points in its life at once — egg, caterpillar, pupa, adult — in a single image. She had reared the animals herself and knew which caterpillar became which moth, information that was frequently wrong or absent in the printed literature.

The plates therefore encode a claim: that an insect is not a specimen but a life cycle, and that the cycle is bound to a particular plant. This is an ecological and developmental argument, made through picture composition, roughly two centuries before either discipline had a name.

Why it is in the collection

Because the intellectual content sits in the layout rather than the text. Merian is doing with arrangement what a later scientist would do with a diagram or a table: asserting relationships — this larva becomes this adult, and both depend on this plant — and making them checkable by putting them in one frame.

She worked as a commercial artist and publisher, sold her own plates, and was read by naturalists across Europe, though her standing was later reduced in accounts that treated her work as illustration rather than research. Restoring that distinction is part of why the record exists.
