Navigation On the left, a symbolic figure of the Wind grasps a sundial and compass. Calm is shown to the right, holding a modern sextant. The moon orbits diagrammatically around the two figures. At the top is an astrolabe, an early astronomical instrument.

"Is not this a true autumn day? Just the still melancholy that I love—that makes life and nature harmonize. ~ George Eliot

The frontispiece to Kepler’s Rudolphine tables (1627). The figures, from left to right, are astronomers Hipparchus, Copernicus, an anonymous ancient observer, Brahe and Ptolemy, each surrounded by symbols of his work. The pillars in the background are made of wood; those in the foreground of brick and marble, symbolizing the progress of astronomy. Astronomical instruments designed by Tycho Brahe serve as decorations. The figures on the cornice symboilize the mathematical sciences, with Urania, the muse of astronomy, in the centre. Kepler’s patron, the Holy Roman emperor Rulodph II, is represented by the Eagle. On the base, from left to right, are Kepler in in study, a map of Brahe’s island of Hven and a printing press

Aeronautics The artist portrays Archytas of Tarentum with his wooden pigeon; then Roger Bacon with his floating ball; Francesco de Lana with a flying boat model; Leonardo da Vinci, whose models perhaps needed only an engine; and Besnier, gliding successfully in 1678.

Astronomy On the left, Arzachel consults his early astronomical tables. John of Hollywood works on an influential astronomical text. Copernicus, who replaced the Earth with the Sun as the center of the solar system, stands near Galileo, whose telescope is dwarfed by a modern version.

The front piece of Galileo’s ‘Dialogue’ (1632). Aristotle (left), shown as a feeble Old man; Ptolemy (centre), wearing a turban because he comes from Egypt; and Copernicus, wearing the clothes of a Polish priest, stand on the shore of the Floretie port of Livorno debating questions of physics and astronomy. But Copernicus looks nothing like the Image of Copernicus that appears in other source, where he is always portrayed as a young and clean-shaven . Indeed, the Latin translation by Bergnegger soon corrected this ‘error’, providing a more accurate representation of Copernicus. It seems Galileo has decided to present himself in the role of Copernicus. Over the heads of the three philosophers hangs the curtain which rises at the beginning of a theatrical performance -- a device that was used by Galileo’s engraver, Sterano della Bella, for the frontpieces of plays. Thus Galileo implies that the argument presented in the book are not to be regarded as true, for Copernicanism had been condemned by the Church. rauterberg.employee.id.tue.nl/lecturenotes/DDM110%20CAS/Galilei-1632%20Dialogue%20Concerning%20the%20Two%20Chief%20World%20Systems.pdf

The telescope is one of humankind's most important inventions, although we’re not entirely sure who to give the credit to. The first person to apply for a patent for a telescope was Dutch eyeglass maker Hans Lippershey (or Lipperhey). In 1608, Lippershey laid claim to a device that could magnify objects three times. His telescope had a concave eyepiece aligned with a convex objective lens. One story goes that he got the idea for his design after observing two children in his shop holding up two lenses that made a distant weather vane appear close. Others claimed at the time that he stole the design from another eyeglass maker, Zacharias Jansen. www.space.com/21950-who-invented-the-telescope.html
