Judah Ben Solomon Ha-Kohen
Judah ben Solomon ha-Kohen (ibn Matkah) ( he, יְהוּדָה בְּן שְׁלֹמֹה הכֹּהֵן (אִבְּן מתקה); 1215– 1274) was a thirteenth-century Spanish people, Spanish Jewish philosopher, astronomer, and mathematician. He was the author of the ''Midrash ha-Ḥokmah'', considered the first of the great Hebrew encyclopedias, and notable for its in-depth treatment both of the exact sciences and of biblical and rabbinic texts. Judah ben Solomon was born and educated in Toledo, Spain, Toledo, the grandson of prominent rabbi Ziza ibn Shushan. He was a pupil of Meir Abulafia, who induced him to study philosophy and Jewish mysticism. At the age of eighteen he entered into correspondence with the philosophers at the court of Emperor Frederick II, Holy Roman Emperor, Frederick II. The emperor himself consulted him about scientific matters, and his answers proved so satisfactory that he was invited in 1247 to settle in Tuscany, where he had free access to the imperial ...

Spanish People
Spaniards, or Spanish people, are a Romance ethnic group native to Spain. Within Spain, there are a number of national and regional ethnic identities that reflect the country's complex history, including a number of different languages, both indigenous and local linguistic descendants of the Roman-imposed Latin language, of which Spanish is the largest and the only one that is official throughout the whole country. Commonly spoken regional languages include, most notably, the sole surviving indigenous language of Iberia, Basque, as well as other Latin-descended Romance languages like Spanish itself, Catalan and Galician. Many populations outside Spain have ancestors who emigrated from Spain and share elements of a Hispanic culture. The most notable of these comprise Hispanic America in the Western Hemisphere. The Roman Republic conquered Iberia during the 2nd and 1st centuries BC. Hispania, the name given to Iberia by the Romans as a province of their Empire, became highly acc ...

Ptolemy
Claudius Ptolemy (; grc-gre, Πτολεμαῖος, ; la, Claudius Ptolemaeus; AD) was a mathematician, astronomer, astrologer, geographer, and music theorist, who wrote about a dozen scientific treatises, three of which were of importance to later Byzantine, Islamic, and Western European science. The first is the astronomical treatise now known as the '' Almagest'', although it was originally entitled the ''Mathēmatikē Syntaxis'' or ''Mathematical Treatise'', and later known as ''The Greatest Treatise''. The second is the ''Geography'', which is a thorough discussion on maps and the geographic knowledge of the Greco-Roman world. The third is the astrological treatise in which he attempted to adapt horoscopic astrology to the Aristotelian natural philosophy of his day. This is sometimes known as the ''Apotelesmatika'' (lit. "On the Effects") but more commonly known as the '' Tetrábiblos'', from the Koine Greek meaning "Four Books", or by its Latin equivalent ''Quadrip ...

Kohanim Writers Of Rabbinic Literature
Kohen ( he, , ''kōhēn'', , "priest", pl. , ''kōhănīm'', , "priests") is the Hebrew word for "priest", used in reference to the Aaronic priesthood, also called Aaronites or Aaronides. Levitical priests or ''kohanim'' are traditionally believed and halakhically required to be of direct patrilineal descent from the biblical Aaron (also ''Aharon''), brother of Moses. During the existence of the Temple in Jerusalem, ''kohanim'' performed the daily and holiday (Yom Tov) duties of korban, sacrificial offerings. Today, ''kohanim'' retain a lesser though distinct status within Rabbinic and Karaite Judaism and are bound by additional restrictions according to Orthodox Judaism. In the Samaritan community, the kohanim have remained the primary religious leaders. Ethiopian Jewish religious leaders are sometimes called ''kahen'', a form of the same word, but the position is not hereditary and their duties are more like those of rabbis than kohanim in most Jewish communities.

Jewish Encyclopedists
Jews ( he, יְהוּדִים, , ) or Jewish people are an ethnoreligious group and nation originating from the Israelites Israelite origins and kingdom: "The first act in the long drama of Jewish history is the age of the Israelites""The people of the Kingdom of Israel and the ethnic and religious group known as the Jewish people that descended from them have been subjected to a number of forced migrations in their history" and Hebrews of historical Israel and Judah. Jewish ethnicity, nationhood, and religion are strongly interrelated, "Historically, the religious and ethnic dimensions of Jewish identity have been closely interwoven. In fact, so closely bound are they, that the traditional Jewish lexicon hardly distinguishes between the two concepts. Jewish religious practice, by definition, was observed exclusively by the Jewish people, and notions of Jewish peoplehood, nation, and community were suffused with faith in the Jewish God, the practice of Jewish (religious) ...

13th-century Jews From Al-Andalus
The 13th century was the century which lasted from January 1, 1201 ( MCCI) through December 31, 1300 ( MCCC) in accordance with the Julian calendar. The Mongol Empire was founded by Genghis Khan, which stretched from Eastern Asia to Eastern Europe. The conquests of Hulagu Khan and other Mongol invasions changed the course of the Muslim world, most notably the Siege of Baghdad (1258), the destruction of the House of Wisdom and the weakening of the Mamluks and Rums which, according to historians, caused the decline of the Islamic Golden Age. Other Muslim powers such as the Mali Empire and Delhi Sultanate conquered large parts of West Africa and the Indian subcontinent, while Buddhism witnessed a decline through the conquest led by Bakhtiyar Khilji. The Southern Song dynasty would begin the century as a prosperous kingdom but would eventually be invaded and annexed into the Yuan dynasty of the Mongols. The Kamakura Shogunate of Japan would be invaded by the Mongols. Goryeo resiste ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

People From Toledo, Spain
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

1 (one, unit, unity) is a number representing a single or the only entity. 1 is also a numerical digit and represents a single unit of counting or measurement. For example, a line segment of ''unit length'' is a line segment of length 1. In conventions of sign where zero is considered neither positive nor negative, 1 is the first and smallest positive integer. It is also sometimes considered the first of the infinite sequence of natural numbers, followed by 2, although by other definitions 1 is the second natural number, following 0. The fundamental mathematical property of 1 is to be a multiplicative identity, meaning that any number multiplied by 1 equals the same number. Most if not all properties of 1 can be deduced from this. In advanced mathematics, a multiplicative identity is often denoted 1, even if it is not a number. 1 is by convention not considered a prime number; this was not universally accepted until the mid-20th century. Additionally, 1 is the s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nur Ad-Din Al-Bitruji
Nur ad-Din al-Bitruji () (also spelled Nur al-Din Ibn Ishaq al-Betrugi and Abu Ishâk ibn al-Bitrogi) (known in the West by the Latinized name of Alpetragius) (died c. 1204) was an Iberian-Arab astronomer and a Qadi in al-Andalus. Al-Biṭrūjī was the first astronomer to present a non-Ptolemaic astronomical system as an alternative to Ptolemy's models, with the planets borne by geocentric spheres. Another original aspect of his system was that he proposed a physical cause of celestial motions. His alternative system spread through most of Europe during the 13th century. The crater Alpetragius on the Moon is named after him. Life Almost nothing about his life is known, except that his name probably derives from Los Pedroches (al-Biṭrawsh), a region near Cordoba. He was a disciple of Ibn Tufail (Abubacer) and was a contemporary of Averroes. Planetary model Al-Bitruji proposed a theory on planetary motion in which he wished to avoid both epicycles and eccentrics, and to a ...

Tetrabiblos
''Tetrabiblos'' () 'four books', also known in Greek as ''Apotelesmatiká'' () "Effects", and in Latin as ''Quadripartitum'' "Four Parts", is a text on the philosophy and practice of astrology, written in the 2nd century AD by the Alexandrian scholar Claudius Ptolemy ( AD 90– AD 168). Ptolemy's ''Almagest'' was an authoritative text on astronomy for more than a thousand years, and the ''Tetrabiblos'', its companion volume, was equally influential in astrology, the study of the effects of astronomical cycles on earthly matters. But whilst the ''Almagest'' as an astronomical authority was superseded by acceptance of the heliocentric model of the Solar System, the ''Tetrabiblos'' remains an important theoretical work for astrology. Besides outlining the techniques of astrological practice, Ptolemy's philosophical defense of the subject as a natural, beneficial study helped secure theological tolerance towards astrology in Western Europe during the Medieval era. This allowed Pt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Almagest
The ''Almagest'' is a 2nd-century Greek-language mathematical and astronomical treatise on the apparent motions of the stars and planetary paths, written by Claudius Ptolemy ( ). One of the most influential scientific texts in history, it canonized a geocentric model of the Universe that was accepted for more than 1,200 years from its origin in Hellenistic Alexandria, in the medieval Byzantine and Islamic worlds, and in Western Europe through the Middle Ages and early Renaissance until Copernicus. It is also a key source of information about ancient Greek astronomy. Ptolemy set up a public inscription at Canopus, Egypt, in 147 or 148. N. T. Hamilton found that the version of Ptolemy's models set out in the ''Canopic Inscription'' was earlier than the version in the ''Almagest''. Hence the ''Almagest'' could not have been completed before about 150, a quarter-century after Ptolemy began observing.
