Galileo Galilei - Law 1: Never Outshine the Master - Observance Of The Law lyrics

In the early 1600s, the Italian astronomer and mathematician Galileo found himself in a precarious position. He depended on the generosity of great rulers to support his research, and so, like all Renaissance scientists, he would sometimes make gifts of his inventions and discoveries to the leading patrons of the time. Once, for instance, he presented a military compa** he had invented to the Duke of Gonzaga. Then he dedicated a book explaining the use of the compa** to the Medicis. Both rulers were grateful, and through them Galileo was able to find more students to teach. No matter how great the discovery, however, his patrons usually paid him with gifts, not cash. This made for a life of constant insecurity and dependence. There must be an easier way, he thought. Galileo hit on a new strategy in 1610, when he discovered the moons of Jupiter. Instead of dividing the discovery among his patron--giving one the telescope he had used, dedicating a book to another, and so on--as he had done in the past, he decided to focus exclusively on the Medicis. He chose the Medicis for one reason: Shortly after Cosimo I had established the Medici dynasty, in 1540, he had made Jupiter, the mightiest of the gods, the MEdici symbol--a symbol of a power that went beyond politics and banking, one linked to ancient Rome and its divinities. Galileo turned his discovery of Jupiter's moons into a cosmic event honoring the Medicis' greatness. Shortly after the discovery, he announced "the bright stars (moons of Jupiter) offered themselves in the heavens" to his telescope at the same time as Cosimo II's enthronement. He said that the number of the moons--four--harmonized with the number of the Medicis (Cosimo II had three brothers) and that the moons orbited Jupiter as these four sons revolved around Cosimo I, the dynasty's founder. More than coincidence, this showed that the heavens themselves reflected the ascendancy of the MEdici family. After he dedicated the discovery to the MEdicis, Galileo commissioned an emblem representing Jupiter sitting on a cloud with the four stars circling about him, and presented this to Cosimo II as a symbol of his link to the stars. In 1610 Cosimo made Galileo his official court philosopher and mathematician, with a full salary. For a scientist this was the coup of a life-time. The days of begging for patronage were over.
