Curiosity
Secondo la leggenda, un giorno imprecisato del 1608 i figli di Hans Lipperhey, che era un occhialaio di Middelburg , stavano giocando nel laboratorio del padre con delle lenti. When one of the sons put a concave lens next to his own eye, holding a convex lens in his other hand, and reaching out his arm in the direction of the tip of the cathedral bell tower he looked through it, he saw the wind-marking rooster at the top grow larger and closer. Immediately showing the phenomenon to his father, he fixed the lenses on a plank to make observation easier, thus creating the first rudimentary telescope.

Galilei never claimed the invention of the telescope, but della Porta, feeling defrauded of the invention, wrote in a letter to Federico Cesi in 1609: “…of the secret of the telescope I have seen it et it is a coglioneria, et it is taken from my book IX De Refractione…” Indirectly disproving della Porta, when Galilei showed the telescope to some senators of the Venetian Republic, the astonishment it aroused was enormous.
