Juliuse kalender (varasem µigekiri juuliuse kalender ) on kalender , mille kehtestas Julius Caesar 46 eKr ning mis jµustus 45 eKr ehk 709 ab urbe condita See kalender valiti p¤rast konsulteerimist Sosigenesega ning selle ilmne eesm¤rk oli saada l¤hendus troopilisele aastale sellisena, nagu teda tol ajal tunti. Juliuse kalendris on 365-p¤evane aasta, mis jaguneb 12 kuuks, ja liigp¤ev , mis lisatakse iga 4 years. See kalender j¤i mµnes riigis kasutusele kuni 20. sajandini v¤lja ning mµned µigeusu kirikud Jeruusalemma •igeusu Kirik Vene •igeusu Kirik Gruusia •igeusu Kirik ja Serbia •igeusu Kirik kasutavad seda t¤nini. Selle kalendri j¤rgi lisatakse vµrreldes astronoomiliste aastaaegadega liiga palju liigp¤evi, nii et aastaajad saabuvad kalendris igal aastal keskmiselt ¼he minuti vµrra varem. Caesar olevat sellest mittevastavusest k¼ll teadlik olnud, kuid pidas seda v¤het¤htsaks. 16. sajandil viidi l¤bi kalendrireform ning kehtestati Gregoriuse kalender , mis suurendas t¤psust kevadise p¶¶rip¤eva aja suhtes, kuid muutused olid suhteliselt v¤ikesed.

Abstract My PhD Dissertation, Sacrobosco in Spanish, belongs to a research project financed by the Spanish Ministry of Science and Technology whose title is Translation and science: genesis of the Castilian (Spanish) as language of science . This project focuses on the history of medicine and the exact sciences, in particular astronomy, during the Middle Ages in Spain; therefore, my current work deals with the history of the Castilian language for specific purposes, the history of translation and the history of astronomy.
John of Holywood or Johannes de Sacrobosco, his Latin name, was an astronomy and mathematics professor in the University of Paris in the thirteenth century. Due to his academic work, he wrote, among other textbooks in Latin, one on some basic notions about astronomy and cosmography based on the ptolemaic tradition: De Sphaera Mundi. It was so clear and elementary that it soon became the most used textbook in the majority of the western European universities from the thirteenth to the seventeenth century, being translated to several languages, such as Spanish.
Focusing on the fifteenth and sixteenth century Spanish translations of De Sphaera Mundi, my dissertation will consist of a transcription or critical edition of the texts, most of them unpublished, in order to be able to compare the scientific discourse and study the astronomical terms used to translate the Latin original into Spanish.

    Our CD Top 20 In 1453, Constantinople fell to the Turks, ending the Byzantine empire. This date also marks the beginning of the Renaissance, since the waves of Greek refugees spread knowledge of Greek throughout Europe. Included with the newly available Greek manuscripts were the Corpus Hermetica, Plotinus, and the works of the Neoplatonists.
    Shortly thereafter in 1492, Isabella and Ferdinand expelled the Jews from Spain. This sent waves of Jewish refugees throughout Europe, spreading knowledge of Hebrew and of the Kabbalah.
    Renaissance philosophers sought to integrate these traditions with the view of unifying the rapidly disintegrating religious factions and also ending the constant political strife. Thus they are the forerunners or prophets of the Rosicrucian and Illuminati movements.

    with Sacro Bosco's Sphaera mundi , Alchabitius' Libellus isagogus and Ibn Ezra's De luminaribus et diebus creticis bound in The solar eclipse of August 11, the recent anniversary of thirty years since the first man stepped on the moon, plus our increasing calendrical obsession as the new millennium approaches, makes our first book of the month a volume of four astronomical works bound together a particularly apt choice. Instrument with two moveable volvelles to show the motion of the moon Printed calendars and almanacs became extremely popular in the fifteenth century and provided ordinary people with the basic knowledge required to plan their daily routines. The market for calendars was first tapped by Gutenburg, who published a calendar which calculated the times of new and full moons and planetary positions, with readings every two to three days. All earlier calendars, however, were superseded by those of Regiomontanus (1436-1476) whose calculations were far more accurate; he recorded several eclipses of the moon and his interest led him to make the important observation that longitude at sea could be determined by calculating lunar distances. Outstanding also is his observation of a comet in 1472, 210 years before it was "first" seen by Halley.
