Ashvamedha, Rituals

Standing Scholarly debate

Concerns Origin Period Start Year

Currently States -1400

The rite is described in the Rig Veda's two horse-sacrifice hymns, its own text says, but the Rig Veda's own composition date is a long-running scholarly dispute: the dominant linguistic view places its main body between 1500 and 1200 BCE, some scholars citing Mitanni treaty references to Vedic gods around 1400 BCE, while others argue for a considerably earlier date on different textual and geological grounds. No single year commands agreement.

Asmita, Vices

Standing Scholarly debate

Concerns Origin Period

Currently States Named within the Yoga Sutra, a text whose own compilation and dating remain unsettled among scholars: traditional accounts place Patanjali well before the Common Era, while modern philological scholarship has proposed dates ranging from roughly the second century BCE to as late as the fourth or fifth century CE, with the text possibly compiled from older material rather than composed at a single sitting.

Asmodeus, Mythical Creatures

Standing Scholarly debate

Concerns Lineage

Currently States Some rabbinic and later Kabbalistic sources make Ashmedai a king over a whole demonic court with named subordinates and a demon wife, Lilith among the figures sometimes linked to that court in later, non-Talmudic folklore, while the Talmud itself is more restrained and treats him mainly as a single cunning individual rather than the head of a fully elaborated hierarchy; this atlas records the Talmudic account as the earliest attested and the courtly elaborations as later folkloric growth rather than settled doctrine.

Asphodel Meadows, Realms

Standing Scholarly debate

Concerns Origin of the Name

Currently States The earliest source is Homer's Odyssey, Book Eleven, where the shade of Achilles is described walking a meadow of asphodel; philologists have long debated whether Homer's word asphodelos names the familiar white-flowered plant at all, since its original meaning was reportedly already unclear to later Greek readers, a genuine and still unsettled point rather than a simple botanical identification.

Áss, Younger Futhark Runes

Standing Scholarly debate

Concerns Meaning in the Attesting Source

Currently States Dickins's Runic and Heroic Poems of the Old Teutonic Peoples (Cambridge University Press, 1915) records the sharpest divergence between the two rune poem traditions at Ass, the fourth rune of the Younger Futhark: the Norwegian poem reads it as a river mouth or estuary, a landscape feature, while the Icelandic poem reads the same rune as Ass, a god, understood by editors including Dickins to mean Odin specifically, one place name and one deity for an identical rune.

Assembly of the Taoist Deities (Yongle Palace), Sacred Art & Iconography

Standing Scholarly debate

Concerns Depicted Subject

Currently States A grand procession of Taoist deities, celestial officials, immortals, planetary and stellar spirits, and attendant guardian and musician figures, arranged hierarchically and moving toward the eight principal deities at the composition's center, who lead the assembly in paying homage to Yuanshi Tianzun. Sources consulted give different totals for how many figures the mural contains, ranging from 286 to roughly 292; the discrepancy appears to depend on whether a count covers only the primary west wall scene or the full mural across all four walls and the screen wall, since the west wall alone is separately reported at 286 figures across 403 of the mural's total 400 to 430 square meters.

China Daily's Shanxi edition gives 286, specified as the west wall alone (403 square meters of the mural's roughly larger total); other aggregated accounts consulted during research give 289, 290 or 292 for the full hall. Recorded as debated rather than resolved to a single number because no source consulted explains its own counting method precisely enough to reconcile the figures with confidence.

Asteya (Non-Stealing), Virtues

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 asteya named third, 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 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.

Concerns Origin Period

There is no scholarly consensus on a single date for the Yoga Sutras.

Standing Scholarly debate

According To Seven-layer aura (Barbara Brennan, Hands of Light)

Kurt Leland's Rainbow Body: A History of the Western Chakra System from Blavatsky to Brennan (Ibis Press, 2016), which traces the aura and chakra literature through to Brennan, dates Barbara Ann Brennan's Hands of Light, the same book credited elsewhere on this page with fixing the seven named aura layers and their pairing with the seven chakras, to 1987 by its publisher's catalogue record, while some other library catalogues list the same first edition as 1988. Leland notes the one-year discrepancy without resolving it; it most likely reflects the ordinary gap between a book's stated copyright year and its public release the following year, a common source of one-year catalogue disagreements. The atlas's own articles on the aura layers follow 1987, and this property records that year while flagging the alternative rather than asserting either flatly.

Astrolabium Planum, Esoteric Texts

Standing Scholarly debate

Concerns How Its Legacy Is Contested

Currently States The degree images are attributed within the book to Pietro d'Abano rather than claimed by its compiler. How much of the material is his, and where he had it from in turn, is unresolved.

The Astrolabium Planum, printed by Erhard Ratdolt in 1488 and carrying an image for each of the 360 degrees of the zodiac, credits the fourteenth century physician and astrologer Pietro d'Abano as the source of its decan and degree imagery. The 1488 printed edition is the primary text cited here. The method available is textual and art-historical comparison: reading the book's own framing language, which presents the images as received and credits d'Abano without specifying which images he originated and which he passed on from an earlier tradition, against what independent evidence survives of d'Abano's own writing and of earlier degree-image traditions circulating before 1488. Because no manuscript or text earlier than the printed book itself has been identified that would show which specific images are d'Abano's own contribution and which he inherited, the book's self-presentation as compiling received material under his name cannot be verified or disproved from the surviving record, and the question of what belongs to him personally stays open.

Astronomy, Scholarly Disciplines

Standing Scholarly debate

Concerns Emerged As Named Discipline

Currently States 1687

Astronomy's own description already records that it "diverged as separate disciplines [from astrology] in the early modern period"; historians place the split at different marks depending on which kind of separation is meant: Copernicus's 1543 De Revolutionibus (the mathematical break with geocentrism), Kepler and Galileo's telescopic observation in the early 1600s (the empirical break), or Newton's 1687 Principia Mathematica (the point at which celestial mechanics became a fully mathematical, non-astrological physical science, the value recorded here). No single year commands consensus; this is a real scholarly disagreement with named positions, not an unanswered question.

Asz ࡑ, 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.

Scholars have proposed several correlations between the xiuhpohualli year and the Gregorian calendar. The month range given here follows one widely reproduced reconstruction and is offered for relative placement only, not as a settled date: the 365 day count carried no intercalated leap day, so its alignment with the solar year is understood to have drifted across the centuries of its use, and colonial era testimony was recorded decades after the practice had ended.

Aten, Deities

Standing Scholarly debate

Concerns Theology

Currently States Monotheistic: one God

Whether Akhenaten's Atenism was a true monotheism, denying that other gods existed at all, or a monolatry or henotheism that elevated one god to sole worship without denying the others' existence, is argued from the same evidence: the Aten displaced every other cult for about seventeen years, the name of Amun was chiselled from monuments across Egypt, and the god was given a form, a disc with rays ending in hands, no other Egyptian god had ever taken. Erik Hornung's Akhenaten and the Religion of Light (2001) is the standard modern study of the reform's theology, treating the reform's suddenness and its total collapse within a generation of Akhenaten's death as evidence of how unlike anything else in Egyptian religion it was, without treating the monotheism question itself as closed.

Athanasian Creed, Creeds & Confessions

Standing Scholarly debate

Concerns Place of Origin

Currently States J. N. D. Kelly's The Athanasian Creed (Adam and Charles Black, 1964), the standard scholarly study of the text, argues for southern Gaul as the creed's place of origin on the evidence of its Latin vocabulary, which parallels writers of that region, and its early liturgical use within the circle of Caesarius of Arles, since the creed itself, known from its opening words as the Quicunque Vult, names no author, no place and no occasion for its own composition.

Other placings and dates have been proposed since the text names no author, no place and no occasion for its own composition, and Kelly's case for southern Gaul around the year 500 rests on argument from vocabulary and later liturgical use rather than on any internal statement.
