The graphic entertainment in representing the monstrous can be seen in the illustrations in Suite de conjectures physiques, from 1708 (digital copy), by Nicolaas Hartsoeker (1656-1725), better known as a physicist, for having perfected the microscope along with Huygens. Thanks to observations made with the new instrument, he suggested the presence of "homunculi" in the semen, as noted in the seventh lecture of the work De la generation: "Que la semence des animaux est remplie d'une infinite d'animaux... d'une figure un peu ovale avec une queue d'une prodigieuse longueur" (p. 106). One paragraph is dedicated to monsters and the story of Jean Baptiste and Lazare is told. They are Siamese twins born near Genoa in 1617 and they travelled throughout Europe. The author learnt about them from Thomas Bartholin and Liceti and they are presented in stylish clothes of the seventeenth century, accompanied by "beaucoup de présence d'esprit" (p. 133, pl. III).

An example of vivid graphic divertissement on monstrosities can be seen in two plates found in the 1761 Trattato chirurgico by Angelo Nannoni (1715-1790) (digital copy), in which two cases of enormous scrotum tumours are illustrated; the first "with due respect" of the Jesuit Father suffering from it which had "truly become a subject of wonder about this very respectable Religious person".
