Standing Scholarly debate

Concerns Lineage

Currently States By Hesiod's account in the Theogony, born motherless from the sea foam produced when the severed genitals of Uranus fell into the sea; Homer's Iliad instead names her daughter of Zeus and the goddess Dione.

Hesiod (Theogony) and Homer (Iliad) give genuinely different ancient accounts of her origin, not a single story told two ways: Hesiod makes her motherless and born of the sea, Homer makes her the daughter of Zeus and Dione.

Apocalypto (2006 Film), Screen Works

Standing Scholarly debate

Concerns Religious Subject Matter

Currently States Depicts a Maya city's priesthood performing sacrifice before a large audience amid a solar eclipse, a warrior culture raiding villages for captives, and a civilization the film frames as collapsing partly under its own environmental strain, deforestation and soil exhaustion among the pressures shown. The film is set in the Late Postclassic period, shortly before Spanish contact, and its Maya characters speak Yucatec Maya throughout.

Archaeologists Lisa Lucero and David Webster, quoted in a USA Today article, and Zachary Hruby, quoted in National Geographic, argued the film's scale of sacrifice, its raiding for captives and its compressed timeline more closely resemble Aztec practice or conflate periods roughly four hundred years apart than they reflect documented Maya history. Mesoweb's own analysis, written by Maya specialists answering that critique directly, holds that the film's chosen setting, the Late Postclassic rather than the Classic period, is one where mass sacrifice and the Yucatec language are in fact both documented, so the criticism rests on a period the film never claims to depict. The disagreement is unresolved between the two camps as documented.

Apollo, Deities

Standing Scholarly debate

Concerns Origin of the Name

Currently States The etymology of the name Apollo is genuinely unsettled among classicists. Proposals include a Doric root tied to apella, a tribal assembly, an origin in the Hittite god Appaliunas invoked in a Bronze Age treaty, and a derivation from a word for destruction reflecting his role as a plague sending archer in the Iliad. No single reading commands consensus, and the Oxford Classical Dictionary treats the question as open.

Concerns Origin Period Start Year

Currently States 750

Historians differ on which stage of the creed's growth counts as its origin. Its earliest ancestor, the Old Roman Symbol, is recorded separately in this atlas at around 150. The wording now called the Apostles' Creed, its received text, is not fully attested until a document associated with Priminius, written around 710 to 750. 750 is recorded here for the developed text this entry describes, not for its older ancestor.

Apple, Plants

Standing Scholarly debate

Concerns Origin of the Name

Currently States From Old English aeppel, a widely attested ancient Germanic word whose deeper Indo-European root is not settled among linguists.

According To Herbals: Their Origin and Evolution

Aeppel is securely Germanic and shared across the old Germanic languages, but historical linguists disagree on its ultimate Indo-European root: proposals connect it to words for fruit generally, to a place name, or to no securely reconstructible ancestor at all, so no single derivation beyond Germanic is treated as settled here.

April, Months of the Year

Standing Scholarly debate

Concerns Origin of the Name

Currently States Contested since antiquity: Varro derived Aprilis from aperire, to open, for the opening buds of spring, while Ovid derived it from Aphrodite and gave the month to Venus; modern scholarship adds the Etruscan Apru

Two derivations were current in antiquity itself, Varro's aperire against Ovid's Aphrodite, and modern philology adds an Etruscan candidate without settling the question.

Standing Scholarly debate

Concerns Lifespan or Floruit Start Year

Currently States 124

No ancient source states Apuleius's exact birth year. Historians of Roman literature cite around 124 CE as the conventional estimate, derived from references within his own Apologia to his age and career stage at the time of his trial, rather than from a direct record.

No ancient source records Apuleius's death directly.

Aq ࡒ, 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.

Aquaquam, Sacred Dances

Standing Scholarly debate

Concerns Historical Origin

Currently States Ethiopian tradition credits the whole chant system, and with it the movement that belongs to it, to Saint Yared, a deacon of Aksum in the sixth century.

That Yared existed and that the system bears his name are not in question. How much of the surviving chant and movement goes back to the sixth century is, since the notation is far later than he is and the tradition was oral for centuries. Scholars differ on how much weight the attribution can carry.

Araba, Religious Roles & Titles

Standing Scholarly debate

Concerns Point in Dispute

Currently States Whether the Araba Agbaye of Ile-Ife, the senior babalawo who casts on behalf of his own town rather than any individual, holds authority over Ifa houses outside Yorubaland is not settled. J. Lorand Matory's Black Atlantic Religion (Princeton University Press, 2005) records that some diaspora bodies accept the Ile-Ife office's wider claim while others hold that a house answers only to its own initiatory lineage.

A genuine disagreement about jurisdiction, not about the existence or seniority of the Ife office itself.

Arabesque, Sacred Geometry

Standing Scholarly debate

Concerns Meaning in the Attesting Source

Currently States Whether the arabesque encodes a doctrine, infinity, the unity of God, the dissolution of fixed form, is debated. Perennialist writers read it as visual theology; historians such as Kuhnel and Necipoglu treat those readings as modern projections onto a formal, workshop-driven tradition.

Two live camps: perennialist and symbolist readings of Islamic ornament as theology, against the art-historical position (Kuhnel; Necipoglu, The Topkapi Scroll) that the sources record workshop geometry, not doctrine.

Archdiocese of Turin, Custodians & Museums

Standing Scholarly debate

Concerns Relevant Holding

Currently States Shroud of Turin, radiocarbon dated in 1988 to approximately 1260 to 1390, a result some researchers continue to dispute

The Archdiocese of Turin has custodianship of the Shroud of Turin, a linen cloth bearing a faint image tradition associates with the burial of Jesus. P. E. Damon and colleagues' Radiocarbon Dating of the Shroud of Turin (1989), published in Nature and based on independent testing at three separate radiocarbon laboratories, dated the cloth sample to the medieval period, roughly the thirteenth to fourteenth centuries, well after the first century the traditional identification requires. Some researchers have since challenged the sampling itself, arguing the 1988 sample was taken from a corner of the cloth that may have been repaired or rewoven with medieval-period material at some point in the shroud's documented history rather than being representative of the original fabric throughout. The method in dispute is the representativeness of a single small sample taken from one location, rather than the radiocarbon method itself, which is not challenged. No subsequent testing accepted by the mainstream scientific community has replaced the original result, which is why the dating remains debated between the standing result and the sampling-location objection to it.

Concerns Era of Composition

Currently States Its narrative frame is set in the Sasanian era, but the surviving text is generally judged by scholars to have reached something like its present form later, with proposed dates ranging from the late Sasanian into the early Islamic period; no firm consensus fixes the date of composition.

The manuscript tradition postdates the narrative's own dramatic setting by an uncertain span, and scholarship has not settled how much of the text as it survives reflects Sasanian-era material against later redaction.

His securely dated reign runs from 224 to 242 CE, but no contemporary record gives his birth year.

Arianrhod, Deities

Standing Scholarly debate

Concerns Point in Dispute

Currently States Scholars disagree about how much of Arianrhod predates the medieval Mabinogion that is her only real source. Some read her as a euhemerized survival of an older Welsh or British goddess connected to the sky and the turning stars, cognate with continental Iron Age goddess figures, while others treat her as substantially a literary creation of the medieval redactor, with no independent cult or earlier attestation behind the name.

Arius, Historical Figures

Standing Scholarly debate

Concerns Theology

Currently States Held that the Son was begotten by the will of the Father and therefore not co-eternal or of one substance with him, so that, in his own phrase, there was when the Son was not.

Athanasius of Alexandria's Orations Against the Arians, written to refute Arius's teaching, is the source through which Arius's position survives at all, since none of his own writings survive except as fragments quoted by hostile opponents. The council that met at Nicaea in 325 CE to judge the dispute, working from summaries of Arius's teaching that the Son was a created being rather than eternally divine, ruled against him and affirmed instead that the Son is homoousios, of one substance with the Father, co-eternal and uncreated. Because Arius's own sustained argument does not survive independently of Athanasius's rebuttal, his theology is known chiefly through the hostile summary the council was judging rather than through his own words, which is why the two positions are named as the Arian and Nicene camps of a controversy whose losing side is preserved only in quotation.

Concerns How Its Legacy Is Contested
