Tengrism as a Modern Name, Doctrines

Standing Scholarly debate

Concerns Point in Dispute

Currently States Whether Tengrism is an invention of tradition, a modern construction assembled out of folklore and scholarship serving an argument about who a people are, or the surfacing of practice that had never stopped and was given a name because it needed one in order to be defended in public. Both are argued in print, and the difference bears on whether Tengrism should be described as an ancient religion at all.

Concerns Approximate Gregorian Span

Currently States Mid to late September

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.

Tertullian, Historical Figures

Standing Scholarly debate

Concerns How Its Legacy Is Contested

Currently States Whether he formally left the church at Carthage for the New Prophecy, and whether a separate body of Tertullianists ever existed, rests on a single passage in Augustine and is read in opposite ways.

Timothy D. Barnes's Tertullian: A Historical and Literary Study (Clarendon Press, 1971) examines the ancient evidence, chiefly Jerome's later claim, for Tertullian's association with and eventual break from the mainstream church over the New Prophecy (Montanist) movement. Barnes's method is historical and philological, reading Tertullian's own later writings for their tone toward the established church against Jerome's explicit claim of formal schism, and finds scholars split into named camps: some accept Jerome's account and read a formal break with the Carthaginian church, while others hold Tertullian's New Prophecy sympathies operated as a rigorist current inside the existing African church rather than as a separate sect he left it for.

Teth ט, Alphabet Letters

Standing Scholarly debate

Concerns Origin Period

Currently States Scholem places Sefer Yetzirah between the second and sixth century CE

According To Sefer Yetzirah: the thirty-two paths and the twenty-two letters

Gershom Scholem's Major Trends in Jewish Mysticism (Schocken Books, New York, 1961) surveys the manuscript recensions of Sefer Yetzirah and finds no single stable text: the surviving copies diverge enough in wording and in the letter-to-planet and letter-to-sign correspondences that quoting "the text" requires naming which recension is meant. Comparing the linguistic style, the doctrinal content and the external references made to the work across centuries of citation, Scholem argues the book could have been composed anywhere from the second to the ninth century CE, a span of roughly a millennium, with later Kabbalistic and Hasidic writers each reading it through their own era's overlay. The atlas follows Scholem's range rather than a narrower guess, and does not print the per-letter planet and sign tables at all, because doing so would silently pick one contested recension over the others.

Tethys, Deities

Standing Scholarly debate

Concerns Origin of the Name

Currently States The etymology of Tethys's own name is unresolved among philologists, and it is a name distinct in origin from the similar-sounding Thetis, mother of Achilles, with whom Tethys is often wrongly conflated.

Philologists have not settled the etymology of Tethys's name: some connect it to a root meaning grandmother or nurse, others treat it as a pre-Greek substrate word with no clear Indo-European derivation. What is certain is that the name is unrelated in origin to the similar-sounding sea nymph Thetis, mother of Achilles, with whom Tethys is frequently confused by modern readers despite the two being unconnected figures in Greek myth.

Thales, Historical Figures

Standing Scholarly debate

Concerns Lifespan or Floruit Start Year

Currently States -624

Encyclopaedia Britannica's Verified Biographies reference (2026) gives Thales's birth as circa 624 to circa 620 BCE, again a range rather than a fixed year, since no contemporary source survives from the seventh century BCE and his dates are inferred entirely from later Greek doxography, chiefly the tradition, recorded by Herodotus, associating him with a predicted solar eclipse. Other ancient reckonings place his birth as early as 625 BCE; this atlas carries the earlier commonly cited figure from that range as one estimate rather than a settled date, since the eclipse-based method of dating him is itself an ancient inference rather than a direct record of his birth.

Currently States -546

Encyclopaedia Britannica's Verified Biographies reference (2026) gives Thales's death as circa 548 to circa 545 BCE, a range rather than a fixed year, reflecting that the only ancient evidence for his life comes from later Greek doxographical tradition, chiefly Herodotus and Diogenes Laertius writing generations to centuries afterward, rather than any document contemporary with Thales himself. Because that later tradition itself gives approximate rather than precise dates, and no earlier corroborating record survives, Britannica's range is carried alongside other ancient estimates as one attested reckoning rather than a settled date.

Thales's Prediction of the Eclipse That Ended the Lydian-Median War, Prophecies

Standing Scholarly debate

Concerns Documented Response

Currently States Modern scholarship disputes that Thales could have genuinely predicted this eclipse to the precision the story implies. D.R. Dicks's foundational study argues that no method available anywhere in the sixth century BCE, including the Babylonian Saros cycle later writers credit Thales with using, could determine the LOCAL VISIBILITY of a specific solar eclipse from a specific place on a specific day, only the general chance of an eclipse occurring somewhere within a period; a correct forecast of this exactness would have required luck, or the story acquired its precision only in the telling, centuries after Thales's own lifetime, the same caution Thales's own page already states about nearly everything credited to him.

Thangtong Gyalpo, Historical Figures

Standing Scholarly debate

Concerns Lifespan or Floruit Start Year

Currently States 1385

Tibetan biographical tradition gives two different chronologies for Thangtong Gyalpo's birth, either 1361 or 1385, more than two decades apart, and no source contemporary with him fixes which is correct. Both pairings are built to preserve his traditionally reported lifespan of about a hundred and twenty five years, which is itself part of the reason scholarship treats the precise year as a hagiographic convention rather than a documented fact; one strand of tradition even reports that upon his 1385 birth he instantly possessed the appearance of a sixty year old, a detail that signals the dates are organized around symbolic longevity rather than ordinary biography.

Tibetan biographical tradition gives two different death years for Thangtong Gyalpo, either 1464 or 1485, paired respectively with the 1385 or 1361 birth year so that his traditionally reported lifespan of about a hundred and twenty five years is preserved either way. No source contemporary with him fixes which pairing is correct, and the round, symbolically loaded span itself is treated by scholars as evidence of hagiographic construction around an already legendary life rather than as a precise biographical record.

According To The Gurmukhi script

Two reference works give incompatible accounts. The Encyclopaedia of Sikhism (Harbans Singh, editor-in-chief, Punjabi University, Patiala, 1998) carries the Sikh tradition that Guru Angad, the second Guru (1504-1552), devised the script. The World's Writing Systems (Peter T. Daniels and William Bright, eds., Oxford University Press, 1996), surveying the paleography of Indic scripts, holds instead that the letterforms were already in mercantile use in the Punjab as one of the Landa scripts descended from Sharada, and that comparing those existing Landa forms against the Gurmukhi letters attested from Guru Angad's era shows a fixing and standardising of a repertoire already in circulation rather than an invention from nothing. Neither side has displaced the other because the two accounts read different kinds of evidence, a community's own historical memory against a comparative script lineage, and the atlas records both without adjudicating.
