Open Questions

Open Axion Estin

Why It Is Open Athonite monastic tradition credits the text to a tenth century revelation to a monk at Karyes, but that account is devotional legend, not a documented event, and no independent manuscript or historical source establishes the hymns actual date or author.

What Would Settle It A dated manuscript witness to the text earlier than, or independent of, the Athonite legend, or a specialist study of Byzantine Marian hymnography that traces the hymns transmission history on textual rather than legendary grounds.

Expertise Needed Byzantine liturgical history; hymnography

Question posed in The Oxford Dictionary of the Christian Church, 3rd revised edition, F. L. Cross and E. A. Livingstone (eds.).

Open Blessed Mantle of the Prophet

Why It Is Open Identification rests on tradition and unbroken custody. The textile has never been radiocarbon dated or otherwise scientifically tested.

What Would Settle It Radiocarbon dating and textile fiber analysis of the cloak, if the Topkapi Palace Museum ever permitted sampling.

Expertise Needed Textile archaeometry, Islamic studies

Question posed in Chamber of the Sacred Relics, Topkapi Palace Museum, Istanbul.

Open Parshvanatha

Why It Is Open Critical scholarship accepts Parshvanatha and Mahavira as historical figures. Jain tradition holds all twenty four to be historical teachers. For the remaining twenty two there is no independent attestation, so a single answer applied across the group would misdescribe most of it in one direction or the other.

What Would Settle It Independent attestation for any individual Tirthankara beyond the two, whether inscriptional, textual from outside the tradition, or archaeological.

Expertise Needed Indology, Jain studies, and South Asian archaeology.

Question posed in The Jains, Paul Dundas, Second edition, page 19.

Open Lily

Why It Is Open The Greek krinon is a general word for a showy flower rather than a botanical name. Anemone coronaria is the most commonly proposed candidate on grounds of what actually grows abundantly and conspicuously in Galilean fields, but Lilium candidum and several others remain in the running and the text gives no distinguishing detail.

What Would Settle It Nothing in the text can settle it; the question would move only on evidence about which flowers were locally called krinon in first-century Galilean usage.

Expertise Needed Koine Greek lexicography and Levantine field botany.

Question posed in Plants in the New Testament, Terry B. Ball, Entry for lily.

Open Thealogy

Why It Is Open The word is variously credited to different writers of the 1970s and this pass could not establish a first attested use from a source it had checked. Goldenberg's use in 1979 is documented; earlier uses are asserted in secondary literature without a locus.

What Would Settle It A first-attestation search across feminist religious periodicals and conference papers of the 1970s, giving a dated printed occurrence with page reference.

Expertise Needed History of religions; lexicography

Question posed in Divinity Atlas Open Questions Register, First Edition.

Open Perth Museum (Culture Perth and Kinross)

Why It Is Open No documentary or physical evidence has ever settled whether monks at Scone hid the genuine stone and gave Edward I a substitute in 1296. The question has never been resolved.

What Would Settle It Discovery of a contemporary thirteenth or fourteenth century record describing the 1296 removal in enough detail to confirm or rule out a substitution, or a comparative petrological study against any stone independently documented as being at Scone before 1296.

Expertise Needed Medieval history, geology

Question posed in Perth Museum (institutional record).

Open Birch (Beth)

Why It Is Open Graves built the thirteen sign sequence in The White Goddess, 1948, by pairing his own reading of the Beth-Luis-Nion tree names to a thirteen month lunar calendar he reconstructed himself. That the wider tree calendar is his modern invention rather than an attested ancient system is not in dispute, and the tree names match because he took them from Ogham. What nobody has examined is the step after that: whether placing a given tree at a given calendar position reflects anything in the surviving Ogham material, or only his argument. No Celtic studies scholar has tested his month by month assignments either way, which is why this is an unfilled gap rather than a disagreement between camps. One question covers all thirteen signs, because the pairing is one act rather than thirteen.

What Would Settle It A philological comparison of Graves's month-by-month tree assignments against the Ogham letter-name glosses preserved in the Auraicept na nEces and the Briatharogam tracts, by a scholar of medieval Irish, to establish whether any assignment beyond the shared name is supportable.

Expertise Needed Celtic studies, medieval Irish philology

Question posed in A Guide to Ogam, Damian McManus.

Open Jaguar

Why It Is Open The were-jaguar infant is one of the most frequent and unmistakable figures in Olmec sculpture, appearing across major sites from San Lorenzo to La Venta. The Olmec left no deciphered textual record explaining their iconography, so nothing establishes whether the figure depicts a mythic birth, a were-jaguar transformation, a ruler's supernatural parentage or something else. Proposed readings are informed guesses drawn from later Mesoamerican parallels rather than conclusions drawn from Olmec sources themselves.

What Would Settle It Decipherment of a securely dated Olmec or Epi-Olmec inscription that names or glosses the figure, or a controlled excavation context, an offering, a burial or a workshop, that ties a were-jaguar sculpture to an identifiable ritual practice.

Expertise Needed Mesoamerican archaeology, epigraphy

Question posed in Encyclopedia of Religion, Mircea Eliade (ed.); Lindsay Jones (ed., 2nd ed.).

Open Salvia Divinorum

Why It Is Open The plant has no confirmed wild population, sets seed poorly and is propagated from cuttings, which points to long cultivation, as with kava and Brugmansia. But there is no colonial record of it, unlike the mushrooms and ololiuqui which the friars documented extensively, and no archaeological evidence. So the plant looks ancient and the documentation begins in the twentieth century.

What Would Settle It Discovery of a wild population would settle the origin. A colonial or pre-conquest reference, possibly under a name not yet connected to it, would settle the antiquity. Genetic work on cultivated clones could estimate how long it has been propagated vegetatively.

Expertise Needed Ethnobotany, plant genetics, Mesoamerican ethnohistory

Question posed in Ethnopharmacology of Ska Maria Pastora (Salvia divinorum, Epling and Jativa-M.), Leander J. Valdes III, Jose Luis Diaz and Ara G. Paul.

Open Ergot

Why It Is Open Proposed by Wasson, Hofmann and Ruck in 1978. It would explain how an experience initiates consistently described as overwhelming could be produced reliably for thousands of people on a schedule. But no ancient source describes anything of the kind, the water extraction needed to separate soluble from toxic alkaloids is delicate, and the argument reasons backwards from the reported effect to a cause that would account for it.

What Would Settle It Residue analysis of vessels securely associated with the Eleusinian rite, or a text that describes the preparation. Absent either, the question may be permanently undecidable, since the Mysteries were kept for roughly two thousand years and the secret held.

Expertise Needed Classics, ancient history, archaeochemistry, mycology

Question posed in The Road to Eleusis: Unveiling the Secret of the Mysteries, R. Gordon Wasson, Albert Hofmann and Carl A. P. Ruck.

Open Soma

Why It Is Open At least three serious candidates have been argued at length and none is established. Wasson proposed Amanita muscaria in 1968; Flattery and Schwartz proposed Peganum harmala in 1989; ephedra is favoured on the grounds that it is the plant used in the living Zoroastrian Yasna, a ritual with no recorded break. Each fits some of the textual evidence and fails on other parts of it.

What Would Settle It A securely dated archaeobotanical find from an Indo-Iranian ritual context with residue analysis, or a philological argument that settles the disputed Rig Veda passages. A fourth possibility deserves testing: that the hymns are liturgical praise rather than pharmacological description, in which case a mild plant is sufficient and the search for a potent one is misconceived.

Expertise Needed Indology, Iranian and Avestan philology, archaeobotany, ethnobotany

Question posed in Soma: Divine Mushroom of Immortality, R. Gordon Wasson.

Open 57

Why It Is Open The anecdote is very widely told and 57 is called the Grothendieck prime because of it. Its literal veracity is disputed within mathematical folklore, and the tellings do not agree on the setting or the wording.

What Would Settle It A first-hand account from someone present, or a contemporary written record of the exchange.

Expertise Needed History of mathematics, and oral history of the Grothendieck circle.

Question posed in Comme Appele du Neant, As If Summoned from the Void: The Life of Alexandre Grothendieck, Allyn Jackson, Part 2, page 1196.

Open Second Sight

Why It Is Open The entire evidentiary record for second sight is testimonial, collected by folklorists across three centuries of Highland tradition. No experimental or quasi-experimental protocol comparing a claimed seer's forewarnings to ordinary hit or miss chance has ever been devised, so there is no data from which any verdict could be drawn either way.

What Would Settle It A prospective, blinded elicitation study: predictions attributed to second sight logged in advance, scored against subsequent events by an independent judge, and compared to a stated chance baseline.

Expertise Needed Folklore studies; parapsychology; statistics

Question posed in The Secret Commonwealth of Elves, Fauns and Fairies, Robert Kirk.

Open Iboga

Why It Is Open Reported since 1962 and repeated many times in unregulated clinics, but the evidence base is weak. Rigorous trials have been slow, partly because the compound is controlled in many jurisdictions and partly because a treatment given once does not fit the commercial model that funds drug development. Meanwhile ibogaine is cardiotoxic, prolongs the QT interval, and deaths have occurred where screening was absent.

What Would Settle It Adequately powered controlled trials with cardiac monitoring. The question is included here rather than left to medicine because the answer bears on the plant: demand from outside Gabon is already driving overharvesting of wild stands of a slow growing species that a religion depends on.

Expertise Needed Pharmacology, addiction medicine, cardiology, conservation biology

Question posed in Bwiti: An Ethnography of the Religious Imagination in Africa, James W. Fernandez.

Open Nefertem

Why It Is Open The name is written nfr plus tm and both halves are ambiguous. It is read as "Atum is beautiful", making the god a statement about the creator, and it is read as "the beautiful one who closes", making it a description of the lotus shutting at dusk. The two readings imply different theologies and Egyptological reference works give both without settling between them.

What Would Settle It An early attestation where the name is written with a determinative or in a context that disambiguates tm as the divine name rather than the verb, or a demonstrably early orthography that rules one reading out.

Expertise Needed Egyptology, philology

Question posed in The Oxford Encyclopedia of Ancient Egypt, Donald B. Redford (ed.).

Open Blue Lotus

Why It Is Open The iconographic case, argued by Emboden, is substantial: the flower is held to the nose with unusual persistence in banquet scenes, some figures appear to be in altered states, and it is linked to wine and to the drinking festivals of Hathor. The pharmacological case is weak. Apomorphine and nuciferine are present in small amounts, apomorphine is a strong emetic rather than a pleasant intoxicant, and no psychoactive dose has been shown achievable from a quantity of flowers a person would plausibly use.

What Would Settle It Quantitative analysis of alkaloid content in Nymphaea caerulea grown under conditions comparable to ancient Egypt, plus a controlled account of the effect of a realistic dose. Residue analysis of vessels from banquet or funerary contexts would help. Note that ololiuqui was doubted on similar grounds for centuries and then vindicated, so an absence of demonstrated activity is not evidence of absence.

Expertise Needed Egyptology, ethnobotany, phytochemistry

Question posed in Transcultural Use of Narcotic Water Lilies in Ancient Egyptian and Maya Drug Ritual, William A. Emboden.

Open Salvia Divinorum

Why It Is Open The plant has no confirmed wild population, sets seed poorly and is propagated from cuttings, which points to long cultivation, as with kava and Brugmansia. But there is no colonial record of it, unlike the mushrooms and ololiuqui which the friars documented extensively, and no archaeological evidence. So the plant looks ancient and the documentation begins in the twentieth century.

What Would Settle It Discovery of a wild population would settle the origin. A colonial or pre-conquest reference, possibly under a name not yet connected to it, would settle the antiquity. Genetic work on cultivated clones could estimate how long it has been propagated vegetatively.

Expertise Needed Ethnobotany, plant genetics, Mesoamerican ethnohistory

Question posed in Ethnopharmacology of Ska Maria Pastora (Salvia divinorum, Epling and Jativa-M.), Leander J. Valdes III, Jose Luis Diaz and Ara G. Paul.

Open Lebanon

Why It Is Open No official religious census has been taken in Lebanon since 1932, by policy, to avoid disturbing the sectarian power-sharing arrangement fixed at that count. Every percentage in circulation, including the estimate recorded here, is a modeled estimate rather than a count.

What Would Settle It An official national census that asks and records sectarian religious affiliation, which Lebanese governments have avoided for over ninety years for the same political reason the number stays unknown.

Expertise Needed Demography, political science

Question posed in Religious Composition of the World, 2010-2020, Pew Research Center.

Open The Persinger God Helmet Experiments

Why It Is Open The founding series reported the effect and a double-blind replication at Uppsala in 2005 did not, finding that measured suggestibility predicted the reported experience while exposure to the field did not. Persinger held that the Swedish exposure protocol differed materially from his own. Neither side withdrew, no further trial has been run under a protocol both would accept, and the God helmet continues to be cited in popular accounts of the neuroscience of religion as though the matter were settled in one direction or the other.

What Would Settle It A pre-registered, multi-site, double-blind trial using the field parameters and exposure durations of the original series, with suggestibility measured and entered as a covariate rather than offered as a rival explanation after the fact, and with the analysis plan fixed before data collection.

Expertise Needed Experimental psychology and cognitive neuroscience, working with the psychology of religion

Question posed in Sensed Presence and Mystical Experiences Are Predicted by Suggestibility, Not by the Application of Transcranial Weak Complex Magnetic Fields, Pehr Granqvist, Mats Fredrikson, Patrik Unge, Andrea Hagenfeldt, Sven Valind, Dan Larhammar and Marcus Larsson.

Open Lag BaOmer

Why It Is Open The rabbinic sources report the deaths of Akiva's students as a plague and do not connect them to the revolt. A reading that treats the plague as a veiled account of wartime losses is in circulation, and the counter-reading takes the sources at their word. This pass found no source it could verify on either side, so it wrote no relation between the holiday and the revolt.

What Would Settle It A study of the talmudic and geonic witnesses to the Akiva tradition set against the documentary and archaeological record of the revolt, establishing whether the connection is ancient or a later harmonisation.

Expertise Needed Rabbinic literature; Roman-period Jewish history
