Syrian Rue, Plants

Concerns Contested or Appropriated Modern Use

Currently States Benny Shanon proposed in 2008 that Syrian rue paired with acacia could form a natural DMT and MAOI combination behind Moses' Sinai visions, a hypothesis he labeled speculative himself; the DMT content of the relevant Sinai region acacia species is itself disputed, and no textual or archaeological evidence supports the pairing having been used.

Concerns Chaldean Letter Value

Currently States 4

According To Modern planetary numerology, the scheme called Chaldean

The values recorded here follow Cheiro's Book of Numbers (Cheiro, the pen name of William John Warner, published by Herbert Jenkins, London, 1926), the most widely reproduced version of the so-called Chaldean numerology table. Cheiro's own text names no ancient Chaldean source for the letter values it assigns, and comparing it against other published numerology tables from the same and later periods finds no agreement between them on several letters; no Mesopotamian or Chaldean text has ever been produced that contains a comparable letter-number correspondence. That comparison is why historians of the modern occult treat "Chaldean" as a nineteenth and twentieth century marketing label rather than a checkable lineage claim. The value recorded here is Cheiro's published reading, not a settled fact.

According To The disjoined letters of the Quran

The Study Quran: A New Translation and Commentary (Seyyed Hossein Nasr, editor-in-chief, HarperOne, 2015) surveys the classical and modern commentary tradition on the disjoined letters that open certain suras and reports no consensus reached across fourteen centuries of that commentary. The positions it records include that the meaning is known to God alone, that the letters abbreviate divine names or attributes, that they function as an oath, that they present ordinary letters of the language as a rhetorical challenge, and that some began as scribal or collectors' marks later treated as scripture. Comparing the internal textual evidence, which letters occur and in which suras, against the range of proposed readings, the commentary confirms which letters appear where while confirming that none of the proposed meanings has displaced the others.

Concerns Kept In

Currently States The Ark of the Covenant

The Encyclopaedia Judaica, second edition (Macmillan Reference, 2007), records the biblical narrative account that the Tablets of the Law were kept inside the Ark of the Covenant in the Holy of Holies. The encyclopedia's method is textual, reading Exodus and later biblical references to the Ark's contents, and records this placement per the biblical narrative alone, since both the tablets and the ark that reportedly held them are legendary objects with no surviving physical attestation outside that narrative.

Concerns Existence Basis

Currently States Textual only; no surviving object or archaeological evidence

Two separate reference works reach the same limit from different directions. Edward Ullendorff's Ethiopia and the Bible, the Schweich Lectures of the British Academy, published by Oxford University Press for the British Academy in 1968, examined the Ethiopian tradition that the Ark of the Covenant rests at Aksum, tracing the claim through the Kebra Nagast and finding no independent corroboration earlier than that medieval text itself. The Encyclopaedia Britannica's own current entry on the Tablets of the Law, 2024, likewise finds their existence and fate attested only within the biblical narrative, with no artifact, inscription or external record confirming them. Neither source can go further than the text that first makes the claim, which is why historicity for both is unestablished outside Scripture.

Tai Chi, Disciplines

Standing Scholarly debate

Concerns Key Text

Currently States Tai chi classics, a collected corpus of theoretical texts of debated and multiple authorship

The taijiquan classics are a collected corpus of theoretical texts on principle and practice that different lineages attribute variously, including to the legendary figure Zhang Sanfeng. Douglas Wile's Lost T'ai-chi Classics from the Late Ch'ing Dynasty (State University of New York Press, 1996) is a critical edition and history of these texts. The method is textual and historical criticism, tracing each classic's manuscript history, first datable appearance and transmission within specific family lineages, principally Chen, Yang and Wu, rather than accepting the traditional attribution at face value. Wile's research dismantles the Zhang Sanfeng origin legend, finding no basis connecting the classics to that figure, and traces the corpus instead to accumulated material from the late Qing dynasty. Because individual texts have different, independently traceable histories, both authorship and dating remain disputed among scholars working from the same manuscript evidence.

Concerns Origin Period

Currently States Sikh tradition credits Guru Angad, the second Guru, with giving the script its settled form in the sixteenth century

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.

Taiping Rebellion, Wars & Conflicts

Standing Scholarly debate

Concerns Religious Dimension

Currently States Historians differ over how much weight the Taiping faith itself deserves as a cause rather than a costume. Thomas Reilly argues the movement built a genuinely new religion, fully Christian and fully Chinese, whose theology directly attacked the legitimacy of the Qing state, and Jonathan Spence's narrative likewise treats Hong Xiuquan's visions as central to the war's course rather than incidental to it. Other historians read the rebellion primarily as a social and economic uprising drawing on much older Chinese traditions of millenarian rebellion, in which Christian vocabulary was one more legitimating idiom available to a rebel leader amid regional famine and unrest. Both readings agree the Taiping state's law, calendar and iconoclasm were shaped by its faith; they differ on whether that faith or the underlying social crisis was the deeper cause.

Concerns Death Toll Minimum

Currently States 20000000.000000

The conservative demographic range most general histories of the rebellion use, drawn from population data recorded before and after the fourteen year war. Stephen Platt's history of the conflict reports this range, twenty to thirty million dead, as the figure most consistently cited, attributing the bulk of the toll to the famine, disease and displacement the fighting unleashed rather than to combat deaths alone. This atlas records twenty million as its lower bound on that range.

Concerns Death Toll Maximum

Currently States 70000000.000000

The high end of the spread historians have proposed. Demographic historian Cao Shuji's 2001 reconstruction of Qing era population records put the rebellion's total toll as high as seventy million, a figure Stephen Platt's history reports alongside the standard twenty to thirty million range when discussing how uncertain any single total remains once Qing record keeping collapsed across the war zones. Both figures draw criticism, the low end for undercounting indirect famine and disease deaths in areas that stopped keeping records, the high end for extrapolating too far from incomplete regional data; this atlas records seventy million as the documented upper bound rather than a preferred figure.

Concerns Death Toll Assessment

Currently States The Taiping Rebellion's death toll is among the most disputed in this atlas's whole conflict roster: Stephen Platt's history reports the standard 20 to 30 million range as the most consistently cited reading of pre- and post-war population data, while Cao Shuji's 2001 demographic reconstruction extends the upper bound as high as 70 million. Both figures draw scholarly criticism, the lower end for undercounting indirect famine and disease deaths in areas that stopped keeping records once Qing administration collapsed across the war zones, the higher end for extrapolating too far from incomplete regional data; no historian consulted treats either bound as a settled count rather than a defensible estimate. The rebellion's religious character is also debated rather than assumed: Hong Xiuquan's syncretic Christian theology (he held himself the younger brother of Jesus Christ) was genuinely central to Taiping ideology and iconoclasm, but Platt and other modern historians treat the rebellion's mass violence as driven at least as much by Qing dynastic collapse, regional ethnic tension and civil breakdown as by religious conviction alone.
