Age of Taurus, Ages

Standing Scholarly debate

Concerns Proposed Dating Start Year

Currently States -4000

Nicholas Campion, a historian of astrology (A History of Western Astrology, Continuum, London, 2009), compared two competing methods for locating the boundaries of the zodiacal ages within the roughly 25,800 year precessional cycle. The method the atlas uses for its default date range divides that cycle into twelve equal shares of about 2,150 years each. The rival method Campion documents instead measures the actual, unequal angular width each zodiac constellation occupies along the ecliptic and sets the age boundary where the constellation itself begins or ends. Because the twelve constellations are not equal in width, the two methods place the edges of the Age of Taurus centuries apart, and Campion's survey of the astrological literature finds no consensus on which convention is correct, since the choice is a matter of definition rather than of evidence that could settle it.

Age of Taurus, Ages

Standing Scholarly debate

Concerns Proposed Dating

Currently States One of the twelve ages in the precession of the equinoxes, when the vernal equinox point lay within the constellation Taurus. On the even division of the roughly 25,800 year precessional cycle into twelve shares of about 2,150 years each, the dating this atlas records by default, the age runs from roughly 4000 BCE to 2000 BCE. Nicholas Campion's survey of the astrological literature finds no consensus on this dating, since a rival method that measures each constellation's actual, unequal angular width along the ecliptic instead of dividing the cycle evenly places the boundaries of this age at different centuries.

Marjorie Reeves distinguishes Joachim's own careful, revisable calculation from the firm date-setting of his later followers, who treated 1260 as settled prophecy rather than one output of a complex concordance.

Ah ࡄ, Alphabet Letters

Standing Scholarly debate

Concerns A Rival System's Attribution

Currently States The script's ancestry is assigned either to a cursive form of Aramaic, the derivation favored by most script historians, or to the Parthian chancery script used in Sasanian era administrative documents.

According To The Mandaic script

Both derivations are held in the literature and neither has displaced the other. The Aramaic cursive camp points to the letterforms' overall resemblance to other late Aramaic cursive scripts of the region, including Nabataean and Syriac; the Parthian chancery camp points to specific letterforms, including certain medial and final forms, that resemble Pahlavi documentary hands more closely than any Aramaic cursive exemplar. No single find has settled the question, and Mandaic paleography treats it as open pending further comparative work.

Standing Scholarly debate

Concerns Attributed Author / Compiler

Currently States Traditionally attributed to Patanjali, the compiler of the Yoga Sutras. Scholarship debates whether this is the same Patanjali credited with the Sanskrit grammatical treatise of that name, and whether the text as it stands is the work of a single author or an edited compilation of older material.

Ahimsa (Non-Injury), Virtues

Standing Scholarly debate

Concerns Origin Period

Currently States Dated by scholars anywhere from the second century BCE, on older assumptions of a single ancient author, to as late as the fourth or fifth century CE, on newer philological readings that treat the text as a later compilation. There is no scholarly consensus on a single date for the Yoga Sutras.

Standing Scholarly debate

Concerns Origin Period

Currently States The five mahavratas as a codified set of ascetic vows appear already in the Acaranga Sutra, among the oldest surviving Jain Agamas, with ahimsa named first, though the canon's traditional final redaction at the Council of Valabhi is placed in the fifth century CE, leaving how much of the text predates that redaction unsettled. Their classical formal definition is fixed later in Umasvati's Tattvartha Sutra, a text scholars date anywhere from the second to the fifth century CE.

Standing Scholarly debate

Concerns Scholarly Reception

Currently States Praised in secondary academic discussion, drawing on Jainism specialist Christopher Key Chapple's assessment, for elegantly portraying several Jain leaders and extolling the tradition as a champion of animal rights and nonviolent living. The same discussion records a reservation: the film is said to omit critical inquiry into historical nuance and into the contemporary position of women within Jain religious life, raising questions about gender roles the documentary's own celebratory frame does not address. Both readings come from engagement with the same specialist scholarship rather than from opposed camps, so the film's reception sits between clear praise and a named, unresolved gap rather than at either extreme.

Chapple's assessment, located through secondary academic discussion rather than a directly read primary publication, is the basis for both the praise and the reservation recorded here; a page-cited primary quotation was not independently verified.

Ahir Budhnya, Deities

Standing Scholarly debate

Concerns Textual Note

Currently States Which deep the name refers to has been read three ways: the lower atmosphere, the floor of the sea, and the base or foundation of the world.

According To Vedic Hinduism

Ahir Budhnya, the dragon or serpent of the deep in Vedic hymns, has three competing readings for what budhna, the base or bottom, refers to. Arthur Anthony Macdonell's Vedic Mythology (1897), the standard handbook survey of the Vedic pantheon, records that the atmospheric reading is favoured by the company Ahir Budhnya keeps in the Rigveda's own enumerations of atmospheric deities, that the oceanic reading takes budhna at its most literal sense of a watery depth and places the figure where later Indian serpent deities sit, and that a cosmological reading takes budhna instead as the foundation underlying the cosmos generally. The method is philological, weighing the word's other Rigvedic occurrences and its grammatical company against each of the three readings, since the hymns that name Ahir Budhnya never gloss the term directly. All three are stated positions in the philological literature that can be laid out and compared on the same textual evidence, which is what separates this entry from a case like Aja Ekapada, where the evidence does not even support that much.

Concerns Manner of Death

Currently States Disputed

The Encyclopaedia of Islam, second edition, edited by P. Bearman, Th. Bianquis, C. E. Bosworth, E. van Donzel and W. P. Heinrichs (Brill, 2005), examined the biographical tradition surrounding al-Nasai's death by the same isnad-critical standard his own hadith scholarship applied to others. The account of his death from injuries received after a public dispute over Muawiya appears only in biographical compilations compiled generations after he died, without the kind of continuous chain of transmission back to eyewitnesses that his own Sunan required for a hadith to be accepted, and some of those later compilations place the location of his death differently. Because the very method he pioneered is the method that finds his own death account under-attested, the encyclopedia records the story without accepting it as settled biography.

Standing Scholarly debate

Concerns Notable Publication

Currently States The Divan-i Hikmet, the foundation collection of Turkic Sufi verse, attributed to him. Every surviving manuscript is far later, and the language belongs to a later stage of Turkic than his own.

Devin DeWeese's Islamization and Native Religion in the Golden Horde: Baba Tukles and Conversion to Islam in Historical and Epic Tradition (Pennsylvania State University Press, 1994) examines the Diwan-i Hikmet, the collection of mystical Turkic verse attributed to Ahmad Yasavi, against the manuscript and stylistic evidence for when its individual poems were actually composed. DeWeese's philological method, comparing language and transmission across the surviving manuscript witnesses, finds specialists holding competing positions on how much of the collection can genuinely reach back to Yasavi's own twelfth century, and most read the Diwan as the product of a school of poets that formed around his name and continued composing in his voice for generations afterward rather than as his own single-author work.

Standing Scholarly debate

Concerns Attributes and Iconography

Currently States Mary Boyce's A History of Zoroastrianism (Brill, 1989) records that the winged disc carved on Achaemenid royal reliefs, long popularly read as a depiction of Ahura Mazda presiding over the king, is disputed as such by specialists, since the Gathas and the wider Avesta give Ahura Mazda no visual form and Zoroastrian practice developed no tradition of picturing him directly, so the identification rests on royal Persian art's own visual conventions rather than on any textual description.

Ahura Mazda, Deities

Standing Scholarly debate

Concerns Theology

Currently States Dualist: two opposed cosmic principles

Ahura Mazda is proclaimed the uncreated, wholly good creator, which is the language of monotheism, yet Zoroastrian cosmology sets him in permanent cosmic opposition to the destructive spirit Angra Mainyu, which is the language of dualism, and scholarship has long argued over which description better fits the religion's own theology rather than being a later simplification of it. Mary Boyce's A History of Zoroastrianism (1989), the standard modern history of the tradition, treats this tension as original to Zoroaster's own teaching in the Gathas rather than as a later corruption, which is why the classification here is dualist rather than a simple monotheism, without denying the tradition's own insistence on Ahura Mazda's supremacy and eventual triumph over the lie.
