Galileo Galilei demonstrates one of his early telescopes to Venetian lawmakers. Galileo didn't invent the telescope (that was done by Hans Lippershey), but based upon descriptions he has created his own improved version.

Galileo's first telescope only had about 3x magnification; later he will create a telescope with about 30x magnification.

Today the telescope he is demonstrating is 8x or 9x magnification. He will begin selling his telescopes to merchants who use them at sea and for various trade purposes.
