Galileo's drawing of the moon
Galileo Galilei was an Italian astronomer, commonly known as " Father of Several Sciences". In 1610 he famously published this image of the moon as he had observed it through a telescope. They were released in the Sidereus Nuncius, an astronomical pamphlet which showed detailed observations of the moon and constellations of the stars. Not quite as incredible as the photos of the moon we have seen today, but incredibly impressive for the time!
