Redi, Francesco | Esperienze intorno alla Generazione degl’Insetti

  • First edition of the text that disproved spontaneous generation. First issue without the rare 29th plate which is lacking in most copies.

    “In this scientific attack on the doctrine of spontaneous generation, Redi demonstrated, by means of a series of simple experiments involving sealed, open and gauze-covered flasks of meat, that organic matter remained free of larva when protected from insect contamination... Having shown that insect contagion was necessary before decaying substances could develop worms, redi applied the same principle to parasites found in living creatures. However, he was led astray by his observations into claiming that gall insects were spontaneously generated by the plants housing them, an error that Malphigi corrected in 1679” (Norman 1812).
