Nor was Galileo the first to use the word ‘Telescope,” as some believe, though he was present at the term’s birth. Galileo had been calling his device a ‘perspicillum’ (the English called it a “perspective cylinder”) On April 14, 1611, he attended a dinner held at the Academeia dei Lincei, the scientific organization founded by Federico Cesi in Rome in 1603. Cesi had been inspired to form the scientific society by Giambattista Della Porta’s description of the natural philosopher as an investigator “examining with lynx-like eyes those things which manifested themselves.” After a lavish banquet, the party repaired outside to use one of Galileo’s telescopes to observe Jupiter’s moons and Saturn’s (companions” (not yet recognized as rings). At the dinner the Greek poet and theologian John Demisiam had baptized the instrument ‘telescopio,’ from the Greek for “to see at a distance” ~ Page 61

Once the telescope was in use, it was not long before another, related device was invented: the microscope. Galileo may have been first to use the telescope to view objects close up, thus setting the stage for the invention of the new instrument. A student of his reported that in 1610 Galileo had used an inverted telescope to observe “a certain insect in which each eye is covered with a rather thick membrane, which is perforated with seven holes like a visor of a warrior to allow it sight.” Five years later Giovanni du Pont described how Calileo had used the device to discover that flies could walk upside down on glass because they were “inserting the points of their nails in the pores of the glass.” by sometime between 1620 and 1624, Galileo was constructing a special kind of microscope that he called an ‘occhialiono,’ or little eye, for the purpose of, as he put it, “observing minute objects closely.” ~ Page 62
