Suryadeva Yajvan
Suryadeva (1191 – at least 1248 CE) was a Sanskrit-language writer on astrology and astronomy ('' jyotisha'')) from the Chola kingdom of southern India. He wrote commentaries on several notable works including the ''Aryabhatiya'' and the '' Laghu-manasa''. Biography Suryadeva was a Brahmana of the Nidhruva ''gotra'', associated with the '' Bodhayana Sutra'', claiming descent (pravaras) from the sages Kashyapa, Avatsara, and Naidhruva. His works use different suffixes for his name, including Sūri, Yajvā, Yajvān, Somasut, and Dīkṣita. Sūri refers to his scholarship; the other suffixes suggest that he had performed the Soma-yajna ritual sacrifice. According to his commentary on ''Laghumanasa'', Suryadeva was born in 1191 CE (Monday, 3rd day of the dark half of the Magha month of the Shaka year 1113). He lived in the Chola kingdom, and resided in a town that different manuscripts variously call Gangapuram, Gangapuri, and Shri-ranga-gangapuri; this town can be identified ...

Magha (month)
Magha () is the eleventh month of the Hindu calendar, corresponding to January/February of the Gregorian calendar. In India's national civil calendar, Magha is also the eleventh month of the year, beginning on 20 January and ending on 18 February. In the Hindu lunisolar calendar, Magha may begin on either the new moon or the full moon around the same time of year. It is named thus because in this month, the full moon is usually found nearby or within the star cluster called Magha. Since the traditional Hindu calendar follows the lunar cycle, Magha's start and end dates vary from year to year, unlike the months of the Hindu solar calendars. Magha is a winter ( Shishira Ritu) month. The lunar month of Magha overlaps with the solar month of Makara, which begins with the Sun's entry into Capricorn. Festivals * Shukla Panchami: Vasant Panchami * Shukla Saptami: Ratha Saptami * Maagh Mela is an important festival celebrated by most of North India. * The world-famous "Maha ...

13th-century Indian Astronomers
The 13th century was the century which lasted from January 1, 1201 (represented by the Roman numerals 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) and the destruction of the House of Wisdom. 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 earliest Islamic states in Southeast Asia formed during this century, most notably Samudera Pasai. The Kingdoms of Sukhothai and Hanthawaddy would emerge and go on to dominate their surrounding territories. Europe entered the apex of the High Middle Ages, characterized by rapid legal, cultural, and religiou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
12th-century Indian Astronomers
1 (one, unit, unity) is a number, numeral, and glyph. It is the first and smallest positive integer of the infinite sequence of natural numbers. This fundamental property has led to its unique uses in other fields, ranging from science to sports, where it commonly denotes the first, leading, or top thing in a group. 1 is the unit of counting or measurement, a determiner for singular nouns, and a gender-neutral pronoun. Historically, the representation of 1 evolved from ancient Sumerian and Babylonian symbols to the modern Arabic numeral. In mathematics, 1 is the multiplicative identity, meaning that any number multiplied by 1 equals the same number. 1 is by convention not considered a prime number. In digital technology, 1 represents the "on" state in binary code, the foundation of computing. Philosophically, 1 symbolizes the ultimate reality or source of existence in various traditions. In mathematics The number 1 is the first natural number after 0. Each natural number, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Parameshvara Nambudiri
Vatasseri Parameshvara Nambudiri ( 1380–1460) was a major Indian mathematician and astronomer of the Kerala school of astronomy and mathematics founded by Madhava of Sangamagrama. He was also an astrologer. Parameshvara was a proponent of observational astronomy in medieval India and he himself had made a series of eclipse observations to verify the accuracy of the computational methods then in use. Based on his eclipse observations, Parameshvara proposed several corrections to the astronomical parameters which had been in use since the times of Aryabhata. The computational scheme based on the revised set of parameters has come to be known as the ''Drgganita'' or Drig system. Parameshvara was also a prolific writer on matters relating to astronomy. At least 25 manuscripts have been identified as being authored by Parameshvara. Biographical details Parameshvara was a Hindu of Bhrgugotra following the Ashvalayanasutra of the Rigveda.

Bhāskara I
Bhāskara (; commonly called Bhāskara I to avoid confusion with the 12th-century mathematician Bhāskara II) was a 7th-century Indian mathematician and astronomer who was the first to write numbers in the Hindu–Arabic decimal system with a circle for the zero, and who gave a unique and remarkable rational approximation of the sine function in his commentary on Aryabhata's work. This commentary, ''Āryabhaṭīyabhāṣya'', written in 629, is among the oldest known prose works in Sanskrit on mathematics and astronomy. He also wrote two astronomical works in the line of Aryabhata's school: the ''Mahābhāskarīya'' ("Great Book of Bhāskara") and the ''Laghubhāskarīya'' ("Small Book of Bhāskara"). On 7 June 1979, the Indian Space Research Organisation launched the Bhāskara I satellite, named in honour of the mathematician. Biography Little is known about Bhāskara's life, except for what can be deduced from his writings. He was born in India in the 7th century, and wa ...

Bhattotpala
Utpala, also known as (') was an astronomer from Kashmir region of present-day India, who lived in the 9th or the 10th century. He wrote several Sanskrit-language texts on astrology and astronomy, the best-known being his commentaries on the works of the 6th-century astrologer-astronomer Varāhamihira. Date Utpala dates two of his commentaries on Varāhamihira's works to the year 888 of the ''Shaka kāla''. Assuming that Utpala refers to current year of the Shaka era beginning in 78 CE, these works can be dated to 965-966 CE. * For example, a verse in ''Jagac-candrikā'' - his commentary on the ''Bṛhaj-jātaka'' - states that he finished the work on the 5th day of the bright half of the Chaitra month. This day began on Thursday, 9 March 965 CE and ended on Friday. Utpala states that he completed his work on Thursday. * Similarly, a verse in ''Saṃhitā-vivṛti'' - his commentary on the ''Bṛhat-saṃhitā'' - states that he finished it on the 2nd day of the dark h ...

Vrddha Garga
Garga, also known as Vṛddha Garga ("Garga the Elder"), was an ancient Indian scholar of jyotisha. Several Sanskrit-language jyotiḥśāstra works - covering topics such as astrology, astronomy, and divination - are attributed to him. These works were written over several centuries, and are obviously not the work of a single author. Modern scholars generally date the oldest of these works - '' Gargiya-jyotisha'' - to the 1st century CE, although the source materials for these works may be much older. Biography Garga is also called Vṛddha-Garga ("Garga the Elder") to distinguish him from his later namesakes. He is among the earliest and the most important authors in the jyotisha tradition. ''Mahabharata'' 9.36.14-17 describes him as a prominent astrologer who lived at Gargasrota on the banks of the Sarasvati River. ''Vishnu Purana'' 2.5.26 states that the mythical serpent Shesha was pleased with Garga and taught him astrology, and thus, Garga became capable of predicting fu ...

Gangaikonda Cholapuram
Gaṅgaikoṇḍa Chōḻapuram is a village located near to Jayankondam, Ariyalur district, Tamil Nadu, India. It became the capital of the Chola dynasty in c. 1025 by Chola emperor Rajendra Chola I, Rajendra I, and served as the capital for around 250 years. The town is about approximately northeast of Tiruchirapalli international airport. As of 2014, the ancient city exists as a heritage town in the Ariyalur district of Tamil Nadu, India.

Shaka Era
The Shaka era (IAST: Śaka, Śāka) is a historical Hindu calendar era (year numbering), the epoch (its year zero) of which corresponds to Julian year (calendar), Julian year 78. The era has been widely used in different regions of the Indian subcontinent as well as in Southeast Asia. According to the Government of India, it is referred as the Shalivahana Era (IAST: Śālivāhana). History The origin of the Shaka era is highly controversial. There are two Shaka era systems in scholarly use, one is called ''Old Shaka Era'', whose epoch is uncertain, probably sometime in the 1st millennium BCE because ancient Buddhist and Jaina inscriptions and texts use it, but this is a subject of dispute among scholars. The other is called ''Saka Era of 78 CE'', or simply ''Saka Era'', a system that is common in epigraphic evidence from southern India. A parallel northern India system is the ''Vikrama Era'', which is used by the Vikrami calendar linked to Vikramaditya. The beginning of the S ...
