Pan, Deities

Standing Scholarly debate

Concerns Origin of the Name

Currently States The ancients linked Pan's name to the Greek word for all.

This all-etymology is an ancient folk etymology rather than a settled linguistic derivation. Modern historical linguists generally connect Pan's name instead to an older root associated with pasturing or guarding flocks, fitting his standing as a god of shepherds, so the popular all-reading and the linguistic reconstruction point in different directions and neither has fully displaced the other in how the god is discussed.

Panchamakara, Practices

Standing Scholarly debate

Concerns Point in Dispute

Currently States Whether the five elements were used literally or as prescribed substitutions differs by lineage and by period, and the commentarial literature argues the point itself rather than assuming one reading.

Left-handed Shakta lineages describe literal use within a restricted rite. Right-handed and later lineages prescribe substitutes or read the five as internal yogic operations. Both readings are attested in the primary literature, which is why the question is a genuine disagreement rather than a modern confusion.

Panchen Lama, Religious Offices

Standing Scholarly debate

Concerns Current Status

Currently States Two rival recognitions have existed since 1995: Gedhun Choekyi Nyima, recognized by the fourteenth Dalai Lama days before Chinese authorities took him and his family into custody, has not been seen in public since; Gyaincain Norbu, selected by Chinese authorities using the Qing-era Golden Urn procedure, functions as Panchen Lama within China.

Camps: Tibetan exile institutions hold Gedhun Choekyi Nyima as the legitimate Panchen Lama and consider his whereabouts a serious unresolved human-rights concern; the Chinese state holds Gyaincain Norbu, selected through its own Golden Urn process, as the legitimate Panchen Lama. Neither position is adjudicated here.

Pangu, Deities

Standing Scholarly debate

Concerns Place of Activity

Currently States Whether Pangu ever had a genuinely continuous cult is itself disputed: some Yao and other southern Chinese communities maintain temples and ancestral veneration of a figure called Pangu Wang, King Pangu, which some scholars read as a surviving thread of real local worship rather than literary myth alone, while others treat it as a later, separate folk development only loosely tied to the classical Sanwu Liji account.

Pangu, Deities

Standing Scholarly debate

Concerns Origin of the Name

Currently States The name Pangu has no settled Chinese etymology of its own, and some scholars connect it instead to non-Han linguistic roots from the same southern regions whose surviving Pangu Wang cult practice has been proposed as the myth's ultimate source, an etymological argument that runs alongside, but is distinct from, the debate over the story's textual origins.

Panini, Historical Figures

Standing Scholarly debate

Concerns Lifespan or Floruit

Currently States Panini is usually placed in the fourth century BCE, a dating that, as with his traditional origin-place at Shalatula in Gandhara, rests entirely on indirect argument rather than a contemporary record, since no external document from his own lifetime survives to fix it. The Encyclopaedia Britannica (online academic reference, 2024) gives this fourth century placement as the usual scholarly estimate rather than a settled fact.

Panini, Historical Figures

Standing Scholarly debate

Concerns Place of Origin

Currently States The Encyclopaedia Britannica (online academic reference, 2024) records that Indian tradition places Panini, author of the Ashtadhyayi, the nearly four thousand rules describing the whole of Sanskrit grammar, at Shalatula in Gandhara, near the Indus, the same tradition that also credits Shiva with giving Panini the sounds of his damaru drum as the basis for the grammar's rules; no evidence independent of that tradition fixes his birthplace.

Panini, Historical Figures

Standing Scholarly debate

Concerns Lifespan or Floruit Start Year

Currently States -520

Encyclopaedia Britannica records that experts have assigned Panini to dates spanning the fourth through seventh centuries BCE, with no agreement on the extent of his work either. Max Muller and other Western philologists argued for the fourth century BCE; Indian tradition and some Sanskritists argue for a considerably earlier date, closer to the sixth century BCE, partly on the grounds that the Ashtadhyayi shows no trace of Buddhist vocabulary that a post Buddha grammarian working in the same region might be expected to reflect. A reference in the text to the Yavanas, read by some as evidence of Greek contact and therefore a marker no earlier than the Achaicid era in Gandhara, is itself disputed, since Greeks were present in the Persian empire's eastern satrapies well before Alexander. The marker recorded here follows the range most often cited as the modern working estimate.

Concerns Lifespan or Floruit End Year

Currently States -460

No source distinguishes a death year from a birth year for Panini; the same centuries-wide disagreement recorded under lifespan-start-year applies here, since nothing beyond the Ashtadhyayi and later legendary biography (including the story of his death by a lion, itself treated as folklore rather than record) marks the end of his life. The marker recorded here pairs conventionally with the debated birth estimate and should be read the same way, not as an attested lifespan.

Concerns Approximate Gregorian Span

Currently States Early to late November

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.

Panthay Rebellion, Wars & Conflicts

Standing Scholarly debate

Concerns Religious Dimension

Currently States Historians dispute how central Islam was to the rebellion. The rising is often summarized in general reference works as a Muslim uprising against Qing rule, and Du Wenxiu did take the title of sultan and govern under an Islamic administration blended with existing Chinese institutions. David Atwill's revisionist scholarship argues against reading the rebellion primarily through religion, holding that it was rooted in Yunnan's own multiethnic society and in specific grievances against corrupt and discriminatory provincial governance, with Hui religious identity one factor among several driving a movement that also drew significant Han and Bai support rather than a rebellion of Muslims against non-Muslims as such.

Currently States Conventionally traced to Pope Stephen II, who received a grant of central Italian territory from the Frankish king Pepin the Short, the Donation of Pepin.

According To Papal States (Wikipedia)

Historians differ on when papal temporal rule actually began: some date it to the Donation of Pepin in the 750s, others to the papacy's de facto administration of Rome and its duchy decades earlier as Byzantine authority collapsed in Italy, and the Donation of Constantine invoked at the time to justify it was later shown to be an eighth century forgery.

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.

Papua New Guinea, Countries

Concerns Legal Status

Currently States A constitutional amendment passed by Papua New Guinea's parliament on 12 March 2025, by a vote of 80 to 4, declares Papua New Guinea a Christian country in the constitution's preamble while the government states that section 45, the existing guarantee of freedom of conscience, thought and religion, remains intact; the Sorcery Act of 1971, which had permitted a belief in sorcery to be raised as a legal defence, was repealed in 2013 amid continuing sorcery accusation related violence.

Papua New Guinea's parliament passed a constitutional amendment on 12 March 2025, by a vote of 80 to 4, declaring in the constitution's preamble that the nation acknowledges God, Jesus Christ and the Holy Spirit as its creator and the source of its authority, following consultation work by the Constitutional Law Reform Commission that began in 2022. The amendment also names Christianity in the constitution's Fifth Goal and declares the Bible a national symbol. The government states that section 45, the constitution's pre-existing guarantee of freedom of conscience, thought and religion for all residents, remains legally intact and unaffected, leaving both provisions in the same document without an explicit statement of how they relate should they ever conflict. Separately, the country's 1971 Sorcery Act, which had permitted belief in sorcery to be raised as a legal defence, mitigating culpability for violence committed against a person believed to be a sorcerer, was repealed in 2013, but sorcery accusation related violence has continued despite the repeal, since removing a legal defence does not by itself stop informal community violence carried out under the same belief. Whether the 2025 declaration acquires any practical legal effect beyond its symbolic preamble placement, given section 45's stated survival, is a question that has not yet been tested in Papua New Guinean courts.

Currently States Most paleographic assessments place it between about 175 and 225 CE, making it among the oldest substantial New Testament manuscripts known; some scholars have argued instead for a mid-second century date, around 125 to 150 CE. The manuscript carries no internal date and the range reflects genuine disagreement over comparative handwriting analysis rather than an unsettled question with no proposed answers.

The United States government funded a remote-viewing research programme from 1972 to 1995, run first through SRI International and later through SAIC under the name Star Gate. The American Institutes for Research produced An Evaluation of Remote Viewing: Research and Applications in 1995, a CIA-commissioned review with separate appendices by statistician Jessica Utts and psychologist Raymond Hyman. The method was statistical evaluation of the programme's accumulated experimental results by two independent reviewers with opposing specialities. Utts concluded the statistical pattern indicated a genuine anomalous effect; Hyman concluded the same results were methodologically unreliable. Both reviewers agreed, regardless of that statistical dispute, that the programme's output had no demonstrated operational intelligence value, and the programme was closed the same year on that shared finding.

Parjanya, Deities

Standing Scholarly debate

Concerns Textual Note

Currently States The Vishnu Purana names Parjanya among the twelve Adityas. The Bhagavata Purana list of twelve does not name him and gives Savitr in his place.

According To Puranic Hinduism

Parjanya is named among the twelve Adityas in the Vishnu Purana, one of the two Puranic lists that between them supply the class's canonical membership. The Vishnu Purana and the Bhagavata Purana agree on ten of the twelve names and differ on the remaining two, and Parjanya is one of the two figures the Vishnu Purana includes where the Bhagavata Purana instead names Savitr and Vidhatri. Both are anonymous Puranic compilations transmitted across centuries by different lineages rather than fixed by a single author or date, so the variance cannot be resolved by identifying a copying error in either text. The method, following Arthur Anthony Macdonell's Vedic Mythology (1897), is textual comparison of the two received lists against each other; since the tradition itself hands down both without treating either as the correction of the other, the atlas records the tradition's own disagreement rather than reconciling it.

Parjanya, Deities

Standing Scholarly debate

Concerns Mythic Association

Currently States Set beside the Baltic Perkunas and the Slavic Perun in Indo-European comparison, on the strength of the name.

Parjanya, the Vedic god of rain-bearing storm clouds, has long been compared by Indo-European philologists to the Baltic thunder god Perkunas and the Slavic Perun. Arthur Anthony Macdonell's Vedic Mythology (1897) records the comparison as standard within comparative Indo-European philology but not universally accepted, since the Vedic figure's own domain is rain rather than the thunder its Baltic and Slavic cognates govern, a functional shift an etymological match alone does not explain. The method is comparative historical linguistics, testing whether the names' sound correspondences, tracing all three back to a hypothesised shared Proto-Indo-European root, hold up under the regular sound-change rules the discipline requires, a point philologists have argued over since the comparison was first proposed in the nineteenth century. Because the names may be genuinely cognate while the mythic function drifted apart over the centuries separating the daughter traditions, or the resemblance may be looser than it appears, the comparison remains standard but contested rather than a settled identification.

Parshvanatha, Figures

Standing Scholarly debate

Concerns Historicity

Currently States Historically attested

Paul Dundas's The Jains (Routledge, 2002) examines the evidentiary basis for Parshvanatha's historicity, the twenty-third of the Jain tirthankaras, and finds the evidence entirely internal to the Jain tradition's own scriptural and hagiographical corpus, with no independent external attestation. Dundas records that among the tirthankaras this makes Parshvanatha the earliest figure for whom a historical existence is nonetheless considered plausible by scholars, unlike his predecessors in the Jain lineage, whose historicity is not seriously entertained at all.
