Urania Propitia
''Urania Propitia'' () is a book of astronomical tables written by Maria Cunitz and published in 1650. As Maria Cunitz was the daughter of both a physician and mathematician, it was her ability to grasp complex mathematics quickly and transcribe her findings as a polyglot that allowed her to do what few women had done before her. Introduction ''Urania Propitia'' was a simplification of the ''Rudolphine Tables'' written by Johannes Kepler in 1627. Kepler's dedication to Emperor Ferdinand II which was originally dedicated to Rudolf II was filled with complex and tedious logarithms. Cunitz found many errors within the Rudolphine Tables. The simplifications to these tables were published as the Urania Propitia. In Urania Propitia, Cunitz removed logarithms from Kepler's work, which increased the accuracy and simplified the calculations from the Rudolphine Tables. Cunitz omitted some coefficients from her equations, leading to inaccuracies within her work. Astronomical tables of th ...

Urania
Urania ( ; grc, , Ouranía; modern Greek shortened name ''Ránia''; meaning "heavenly" or "of heaven") was, in Greek mythology, the muse of astronomy, and in later times, of Christian poetry. Urania is the goddess of astronomy and stars, her attributes being the globe and compass. The muse ''Urania'' is sometimes confounded with ''Aphrodite Urania'' ("heavenly Aphrodite") because of their similar name. Family Urania was the daughter of Zeus by Mnemosyne and also a great granddaughter of Uranus. Some accounts list her as the mother of the musician Linus by Apollo or Hermes or Amphimarus, son of Poseidon. Hymenaeus is also said to have been a son of Urania. Function and representation Urania is often associated with Universal Love. Sometimes identified as the eldest of the divine sisters, Urania inherited Zeus' majesty and power and the beauty and grace of her mother Mnemosyne. Urania dresses in a cloak embroidered with stars and keeps her eyes and attention focused ...

Astronomical Tables
In astronomy and celestial navigation, an ephemeris (pl. ephemerides; ) is a book with tables that gives the trajectory of naturally occurring astronomical objects as well as artificial satellites in the sky, i.e., the Position (vector), position (and possibly velocity) over time. Historically, positions were given as printed tables of values, given at regular intervals of date and time. The calculation of these tables was one of the history of computing, first applications of mechanical computers. Modern ephemerides are often provided in electronic form. However, printed ephemerides are still produced, as they are useful when computational devices are not available. The astronomical position calculated from an ephemeris is often given in the Spherical coordinate system, spherical polar coordinate system of right ascension and declination, together with the distance from the origin if applicable. Some of the astronomical phenomena of interest to astronomers are eclipses, apparent ...

17th-century Latin Books
The 17th century lasted from January 1, 1601 ( MDCI), to December 31, 1700 ( MDCC). It falls into the early modern period of Europe and in that continent (whose impact on the world was increasing) was characterized by the Baroque cultural movement, the latter part of the Spanish Golden Age, the Dutch Golden Age, the French '' Grand Siècle'' dominated by Louis XIV, the Scientific Revolution, the world's first public company and megacorporation known as the Dutch East India Company, and according to some historians, the General Crisis. From the mid-17th century, European politics were increasingly dominated by the Kingdom of France of Louis XIV, where royal power was solidified domestically in the civil war of the Fronde. The semi-feudal territorial French nobility was weakened and subjugated to the power of an absolute monarchy through the reinvention of the Palace of Versailles from a hunting lodge to a gilded prison, in which a greatly expanded royal court could be more easily k ...

1650 Books
Year 165 ( CLXV) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Orfitus and Pudens (or, less frequently, year 918 '' Ab urbe condita''). The denomination 165 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years. Events By place Roman Empire * A Roman military expedition under Avidius Cassius is successful against Parthia, capturing Artaxata, Seleucia on the Tigris, and Ctesiphon. The Parthians sue for peace. * Antonine Plague: A pandemic breaks out in Rome, after the Roman army returns from Parthia. The plague significantly depopulates the Roman Empire and China. * Legio II ''Italica'' is levied by Emperor Marcus Aurelius. * Dura-Europos is taken by the Romans. * The Romans establish a garrison at Doura Europos on the Euphrates, a control point for the commerc ...

Greek Mythology
A major branch of classical mythology, Greek mythology is the body of myths originally told by the ancient Greeks, and a genre of Ancient Greek folklore. These stories concern the origin and nature of the world, the lives and activities of deities, heroes, and mythological creatures, and the origins and significance of the ancient Greeks' own cult and ritual practices. Modern scholars study the myths to shed light on the religious and political institutions of ancient Greece, and to better understand the nature of myth-making itself. The Greek myths were initially propagated in an oral-poetic tradition most likely by Minoan and Mycenaean singers starting in the 18th century BC; eventually the myths of the heroes of the Trojan War and its aftermath became part of the oral tradition of Homer's epic poems, the '' Iliad'' and the '' Odyssey''. Two poems by Homer's near contemporary Hesiod, the ''Theogony'' and the '' Works and Days'', contain accounts of the ...

Muses
In ancient Greek religion and mythology, the Muses ( grc, Μοῦσαι, Moûsai, el, Μούσες, Múses) are the inspirational goddesses of literature, science, and the arts. They were considered the source of the knowledge embodied in the poetry, lyric songs, and myths that were related orally for centuries in ancient Greek culture. Melete, Aoede, and Mneme are the original Boeotian Muses, and Calliope, Clio, Erato, Euterpe, Melpomene, Polyhymnia, Terpsichore, Thalia, and Urania are the nine Olympian Muses. In modern figurative usage, a Muse may be a source of artistic inspiration. Etymology The word ''Muses'' ( grc, Μοῦσαι, Moûsai) perhaps came from the o-grade of the Proto-Indo-European root (the basic meaning of which is 'put in mind' in verb formations with transitive function and 'have in mind' in those with intransitive function), or from root ('to tower, mountain') since all the most important cult-centres of the Muses were on mountains or hi ...

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 ...
