Tycho Brahe
Tycho Brahe ( ; born Tyge Ottesen Brahe; generally called Tycho (14 December 154624 October 1601) was a Danish astronomer, known for his comprehensive astronomical observations, generally considered to be the most accurate of his time. He was known during his lifetime as an astronomer, astrologer, and alchemist. He was the last major astronomer before the invention of the telescope. An heir to several noble families, Tycho was well-educated. He took an interest in astronomy and in the creation of more accurate instruments of measurement. He worked to combine what he saw as the geometrical benefits of Copernican heliocentrism with the philosophical benefits of the Ptolemaic system, and devised the Tychonic system, his own version of a model of the universe, with the Sun orbiting the Earth, and the planets as orbiting the Sun. In ''De nova stella'' (1573), he refuted the Aristotelian belief in an unchanging celestial realm. His measurements indicated that "new stars" (''stel ...

Venetian Interdict
The Venetian Interdict of 1606 and 1607 was the expression in terms of canon law, by means of a papal interdict, of a diplomatic quarrel and confrontation between the Papal Curia and the Republic of Venice, taking place in the period from 1605 to 1607. While it was active, the Interdict saw expulsions of some religious orders from Venice, a pamphlet war, and intense diplomacy by France and Spain to resolve the issue. Paolo Sarpi was one of the most prominent Venetian figures involved in the interdict. Background There had been previous interdicts laid on Venice. In 1202 the Venetian siege of Zadar during the Fourth Crusade led Pope Innocent III to excommunicate the army. In 1284, Pope Martin IV imposed an interdict because of Venice's refusal to support a crusade. Pope Clement V addressed escalating measures against Venice after the 1308 capture of Ferrara; and later in the War of Ferrara of the 1480s Pope Sixtus IV laid an interdict on Venice, an erstwhile ally. In 1509 Pope Juliu ...

Pope Paul V
Pope Paul V ( la, Paulus V; it, Paolo V) (17 September 1550 – 28 January 1621), born Camillo Borghese, was head of the Catholic Church and ruler of the Papal States from 16 May 1605 to his death in January 1621. In 1611, he honored Galileo Galilei as a member of the Papal Accademia dei Lincei and supported his discoveries. In 1616, Pope Paul V instructed Cardinal Bellarmine to inform Galileo that the Copernican theory could not be taught as fact, but Bellarmine's certificate allowed Galileo to continue his studies in search for evidence and use the geocentric model as a theoretical device. That same year Paul V assured Galileo that he was safe from persecution so long as he, the Pope, should live. Bellarmine's certificate was used by Galileo for his defense at the trial of 1633. Early life Camillo Borghese was born in Rome on 17 September 1550 into the Borghese family of Siena which had recently established itself in Rome. He was the eldest son of seven sons of the ...

He was a member of the House of Habsburg. Rudolf's legacy has traditionally been viewed in three ways:Hotson, 1999. an ineffectual ruler whose mistakes led directly to the Thirty Years' War; a great and influential patron of Northern Mannerist art; and an intellectual devotee of occult arts and learning which helped seed what would be called the Scientific Revolution. Determined to unify Christendom, he initiated the Long Turkish War (1593–1606) with the Ottoman Empire. Exhausted by war, his citizens in Hungary revolted in the Bocskai Uprising, which led to more authority given to his brother Matthias. Under his reign, there was a policy of toleration towards Judaism. Early life Rudolf was born in Vienna on 18 July 1552. He was the eldest son and success ...
