Maria Sibylla Merian (1647–1717) was born in Frankfurt to the engraver Matthäus Merian the Elder. She trained as a painter and engraver in her father’s workshop, married a Nuremberg painter named Andreas Graff in 1665, separated from him in 1685 (formally divorced 1692), and had supported herself and her two daughters through the 1680s and 1690s by publishing illustrated natural-history books — initially flowers, then caterpillars, then complete insect life cycles.
Her 1679 Der Raupen wunderbare Verwandelung (“The Caterpillar’s Wonderful Transformation”) was the first European illustrated work to document the complete metamorphic life cycles of European Lepidoptera from egg to caterpillar to pupa to adult moth or butterfly. It established her European reputation as a naturalist.
The book was based on observation of the actual life cycles — Merian raised caterpillars at home in glass jars from the egg stage, fed them on identified host plants, and recorded each transition. The Aristotelian doctrine of spontaneous generation still dominated 17th-century European naturalist orthodoxy: insects were widely believed to emerge from rotting matter or mud. Merian’s life-cycle observations were independent confirmation that every insect had specific parents.
Suriname
By 1699 Merian was 52, widowed, and supporting herself in Amsterdam through botanical illustration commissions. The Dutch West India Company colony of Suriname on the northern coast of South America was, in 1699, the most accessible tropical New World destination for an Amsterdam resident. The Dutch had taken Suriname from the English in 1667; by 1699 it was a small Dutch-controlled coastal sugar-plantation economy with approximately 8,000 enslaved Africans, a few hundred enslaved or coerced Indigenous Arawak and Carib labourers, and approximately 1,000 European planters and officials.
Merian sold her Amsterdam paintings collection in spring 1699 to finance the trip. She sailed in June 1699 with her younger daughter Dorothea Maria Graff (then 21). The voyage from Texel to Paramaribo took approximately three months. The two women stayed in Suriname for two years.
What she did there
Merian collected, raised in captivity, observed, and illustrated approximately 90 South American insect species — primarily Lepidoptera but also several beetles, a tarantula (which she illustrated eating a hummingbird, producing one of the period’s most-disputed natural-history images), and at least three species of caiman.
Her field method depended on enslaved Indigenous and African labour. She specifically credited her Indigenous informants — whom she identified by language group and not by personal name — for showing her host plants, specific insect locations, and timing of pupation. She paid for some of the labour. She extracted some of it.
She also documented the abortifacient use of the peacock flower (Caesalpinia pulcherrima) by enslaved Indigenous and African women, who were taking the plant to prevent pregnancies into slavery. The detail appears in her caption to plate 45 of the eventual Metamorphosis Insectorum. It is one of the earliest documented references in any European-language scientific work to a specifically anti-slavery reproductive resistance practice.
She got malaria in approximately spring 1701. The illness was severe enough that she and her daughter cut short the planned five-year expedition. They returned to Amsterdam in September 1701 with about 60 paintings, dozens of specimens, and field notes.
The book
The Metamorphosis Insectorum Surinamensium was published in Amsterdam in 1705. It contained 60 large engraved plates, each showing a single insect species through its complete metamorphic cycle, mounted on its specifically observed host plant. The accompanying text described — in Dutch and Latin in the first edition, and subsequently in additional European-language editions — the observed life cycle, the host plant, and the local Indigenous name for both insect and plant.
The book was an immediate scientific success. Merian sold the second edition’s preliminary subscriptions to European royal courts and scientific societies. The Royal Society in London bought multiple copies. Carl Linnaeus, working on his binomial-nomenclature system fifty years later, cited Merian’s Suriname work as the source for approximately 100 species names — among them Sphinx merianella, named in her honour.
Merian suffered a stroke in 1715 and died in January 1717 in Amsterdam, aged 69. Dorothea Maria Graff continued the family scientific-illustration business in Saint Petersburg under Peter the Great’s patronage. Peter had bought the original Merian Suriname paintings in 1717; they are now in the Saint Petersburg Academy of Sciences archive.
She had founded a discipline by sailing alone to a Dutch colony at 52.
