Resumen
Before the invention of photography in the nineteenth century, scholars of the natural world who wanted to show others the visual image of a plant, an animal, a rock, a fossil or any specimen observed by them had to resort to drawings and paintings. If they were to publish, it was necessary to pour them into some of the engraving techniques in use at the time: from the rustic wood engravings, used in publications shortly after the invention of the printing press, then replaced by the more sophisticated copper engraving and now in the nineteenth century by lithographic stone engraving. In these last two, for special cases they were "illuminated" or colored by hand, with results of extraordinary beauty. And from the 20th century the visual images could be reproduced by chromolithography and other modern techniques.
