{{further|Chi (letter)}}
In antiquity, the [[Christian cross|cross]], i.e. the [[instrument of Christ's crucifixion]] ({{lang|la|[[crux simplex|crux]]}}, {{transliteration|grc|[[stauros]]}}), was taken to be [[Tau cross|T-shaped]], while the [[Chi (letter)|X]]-shape ("[[chiasmus]]") had different connotations. There has been scholarly speculation on the development of the Christian cross, the letter Chi used to abbreviate the name of [[Christ]], and the various pre-Christian symbolism associated with the chiasmus interpreted in terms of "the mystery of the [[Pre-existence of Christ|pre-existent Christ]]".<ref name=Grigg477>{{cite journal |last=Grigg |first=Robert |title="Symphōnian Aeidō tēs Basileias": An Image of Imperial Harmony on the Base of the Column of Arcadius |journal= The Art Bulletin |volume=59 |issue=4 |date= 1977 |pages= 477; 469–482 |doi= 10.2307/3049702|jstor=3049702 }}</ref>

In [[Plato]]'s {{lang|la|[[Timaeus (dialogue)|Timaeus]]}}, it is explained that the two bands which form the "world soul" ({{lang|la|[[anima mundi]]}}) cross each other like the letter Chi, possibly referring to the [[ecliptic]] crossing the [[celestial equator]]:

{{blockquote|And thus the whole mixture out of which he cut these portions was all exhausted by him. This entire compound divided lengthways into two parts, which he joined to one another at the centre like the letter X, and bent them into a circular form, connecting them with themselves and each other at the point opposite to their original meeting-point; and, comprehending them in a uniform revolution upon the same axis, he made the one the outer and the other the inner circle.|source=Plato, {{lang|la|Timaeus}}, 8.36b and 8.36c<ref>[http://www.fullbooks.com/Timaeus3.html 8.36b and 8.36c]</ref>}}

[[Justin Martyr]] in the 2nd century makes explicit reference to Plato's image in {{lang|la|Timaeus}} in terms of a prefiguration of the Holy Cross.<ref>Justin. ''Apologia'', 1.60.</ref> An early statement may be the phrase in ''[[Didache]]'', "sign of extension in heaven" ({{transliteration|grc|sēmeion epektaseōs en ouranōi}}).<ref name=Grigg477 />

An alternative explanation of the intersecting celestial symbol has been advanced by George Latura, claiming that Plato's "visible god" in {{lang|la|Timaeus}} is the intersection of the Milky Way and the Zodiacal Light, a rare apparition important to pagan beliefs. He said that Christian bishops reframed this as a Christian symbol.<ref>{{cite journal|last=Latura|first=George|title=Plato's Visible God: The Cosmic Soul Reflected in the Heavens|journal=Religions|volume=3|issue=3|year=2012|pages=880–886|doi=10.3390/rel3030880|doi-access=free}}</ref>

The most commonly encountered Christogram in English-speaking countries in modern times is the Χ (or more accurately, Chi), representing the first letter of the word ''Christ'', in such abbreviations as ''[[Xmas]]'' (for "Christmas") and ''[[Xian (abbreviation)|Xian]]'' or ''Xtian'' (for "Christian").

An early form of the monogram of Christ, found in early Christian [[ossuaries]] in [[Palestine (region)|Palaestina]], was formed by superimposing the first (capital) letters of the Greek words for [[Jesus]] and [[Christ]], i.e. [[iota (letter)|iota]] '''Ι''' and [[chi (letter)|chi]] '''Χ''', so that this [[monogram]] means "Jesus Christ".<ref name="Bagatti">{{cite book |last=Bagatti |first=Bellarmino |author-link= Bellarmino Bagatti |year=1984 |title=The Church from the Circumcision: History and Archaeology of the Judaeo-Christians |series=Studium Biblicum Franciscanum, Collectio Minor, n.2 |location=Jerusalem |publisher=Franciscan Print.

The [[Alpha and Omega]] symbols may at times accompany the Chi-Rho monogram.<ref>''Allegory of the Church'' by Calvin Kendall 1998 {{ISBN|1-4426-1309-2}} page 137</ref> Since the 17th century, {{lang|la|[[:wikt:chrismon|Chrismon]]}} ({{lang|la|chrismum}}; also {{lang|la|chrismos, chrismus}}) has been used as a [[Neo-Latin]] term for the Chi Rho monogram.

Because the {{lang|la|chrismon}} was used as a kind of "invocation" at the beginning of documents of the [[Merovingian period]], the term also came to be used of the  "[[cross-signature]]s" in early medieval charters.{{efn|While in English literature of the 19th to mid 20th century, {{lang|la|chrismon}} refers to the Chi Rho monogram exclusively, the German-language usage has also come to be adopted in some cases in the specific context of medieval sigla, especially in works translated from German into English, e.g.
Hans Belting, Edmund Jephcott (trans.), ''Likeness and Presence: A History of the Image Before the Era of Art'' (1997), pp. 107–109.<ref>For German usage, see Ersch ''et al''., Volume 1, Issue 29 of ''Allgemeine Encyklopädie der Wissenschaften und Künste'', 1837, [https://books.google.com/books?id=sgxJAAAAcAAJ&pg=PA303 p. 303] {{in lang|de}}.

[[St Cuthbert's coffin]] (late 7th century) has an exceptional realisation of the Christogram written in [[Anglo-Saxon runes]], as ᛁᚻᛋ ᛉᛈᛋ, transliterated to the Latin alphabet as 'IHS XPS', with the ''chi'' rendered as the ''[[eolh]]'' rune (the old ''z'' or ''algiz'' rune) and the ''rho'' rendered as the [[Peorth|p-rune]].

=== IHS ===
[[File:IHS Christogram 1864 Bible.jpg|thumb|IHS Christogram embossed on an 1864 leather-bound King James Bible]]
In the [[Latin]]-speaking Christianity of medieval Western Europe (and so among Catholics and many [[Protestant]]s today), the most common Christogram became "IHS" or "IHC", denoting the first three letters of the [[Greek language|Greek]] name of Jesus, {{lang|grc|ΙΗΣΟΥΣ}}, ''[[iota]]-[[eta (letter)|eta]]-[[sigma (letter)|sigma]]'', or {{lang|grc|ΙΗΣ}}.<ref name=Gieben>''Christian sacrament and devotion'' by Servus Gieben 1997 {{ISBN|90-04-06247-5}} page 18</ref><ref name=Becker>''The Continuum encyclopedia of symbols'' by Udo Becker 2000 {{ISBN|0-8264-1221-1}} page 54</ref><ref name=CathHoly>{{cite web|url=http://www.newadvent.org/cathen/07421a.htm|title=CATHOLIC ENCYCLOPEDIA: Holy Name of Jesus|work=New Advent}}</ref>

The Greek letter ''iota'' is represented by 'I', and the ''eta'' by 'H', while the Greek letter ''sigma'' is either in its lunate form, represented by 'C', or its final form, represented by 'S'. Because the Latin-alphabet letters ''I'' and ''J'' were not systematically distinguished until the 17th century, "JHS" and "JHC" are equivalent to "IHS" and "IHC".

"IHS" is sometimes interpreted as meaning {{langx|grc|ΙΗΣΟΥΣ ΗΜΕΤΕΡΟΣ ΣΩΤΗΡ|Iēsous Hēmeteros Sōtēr|Jesus our Saviour|label=none}} or in Latin {{lang|la|Jesus Hominum}} (or {{lang|la|Hierosolymae}}) {{lang|la|Salvator}}, ('Jesus, Saviour of men [or: of Jerusalem]' in Latin)<ref name=IHS_CathEnc>Maere, René. "IHS." The Catholic Encyclopedia. Vol. 7. New York: Robert Appleton Company, 1910.</ref> or connected with {{lang|la|[[In hoc signo vinces|In Hoc Signo]]}}. English-language interpretations of "IHS" have included "In His Service".<ref name="Bush(NA)2004">{{cite book|last1=Bush|first1=Brian Paige|last2=(NA)|first2=Bush|title=His Blueprint In The Bible: A Study Of The Number Three In Scripture|date=1 March 2004|publisher=Dorrance Publishing Co.|language=English|isbn=9780805963823|page=9}}</ref> Such interpretations are known as [[backronym|backformed acronyms]].

Used in Latin since the seventh century, the first use of ''IHS'' in an English document dates from the fourteenth century, in ''[[Piers Plowman]]''.<ref>{{OED|IHS}}</ref> In the 15th century, [[Saint Bernardino of Siena]] popularized the use of the three letters on the background of a blazing sun to displace both popular pagan symbols and seals of political factions like the [[Guelphs and Ghibellines]] in public spaces (see [[Feast of the Holy Name of Jesus]]).

The IHS monogram with the H surmounted by a cross above [[triclavianism|three nails]] and surrounded by a [[Sol Invictus|Sun]] is the emblem of the [[Jesuits]], according to tradition introduced by [[Ignatius of Loyola]] in 1541.<ref name=IHS_CathEnc />

IHS has been known to appear on gravestones, especially among Irish Catholics.<ref>{{cite book |last1=Romano |first1=Ron |title=Portland's Historic Eastern Cemetery: A Field of Ancient Graves |publisher=Arcadia Publishing |page=87}}</ref><ref>{{cite book |title=New Jersey Cemeteries and Tombstones: History in the Landscape |date=2008 |publisher=Rutgers University Press |page=179}}</ref><ref>{{cite book |title=Irish South Australia: New histories and insights |date=2019 |publisher=Wakefield Press |page=81}}</ref>

=== ICXC ===
In [[Eastern Christianity]], the most widely used Christogram is a four-letter abbreviation, ΙϹ ΧϹ—a traditional abbreviation of the Greek words for 'Jesus Christ' (i.e., the first and last letters of each of the words {{lang|grc|'''Ι'''ΗϹΟΥ'''Ϲ''' '''Χ'''ΡΙϹΤΟ'''Ϲ'''}}, with the [[sigma (letter)#Lunate sigma|lunate sigma]] 'Ϲ' common in medieval Greek),<ref>''Symbols of the Christian faith'' by Alva William Steffler 2002 {{ISBN|0-8028-4676-9}} page 67</ref> and written with [[titlo]] (diacritic) denoting [[scribal abbreviation]] ({{script|Cyrs|І︮С︯ Х︮С︯}}).

On icons, this Christogram may be split: 'ΙϹ' on the left of the image and 'ΧϹ' on the right. It is sometimes rendered as 'ΙϹ ΧϹ ΝΙΚΑ' ({{lang|grc|Ἰησοῦς Χριστὸς νικᾷ}}), meaning 'Jesus Christ Conquers'. 'ΙϹΧϹ' may also be seen inscribed on the [[Ichthys]].

=== Lhq ===
{{see also|Kirishitan}}
[[File:キリシタン灯籠（梅窓院）.jpg|thumb|Lhq-inscription on a Japanese lantern]]
After [[Francis Xavier]] landed in [[Kagoshima]], Japan, in 1549, his missionary work grew and became widely distributed throughout Japan under the patronage of the {{transliteration|ja|[[daimyō]]}}. However, during the [[Edo period]] (1603–1867), Christians were persecuted and forced to hide. Because they were forbidden to openly reverence the images of Christ or [[Mary, mother of Jesus|Mary]], it is believed that they transferred their worship to other carved images and marked them with secret symbols understood only by the initiates. Certain [[Tōrō|Japanese lanterns]], notably the {{transliteration|ja|Kirishitan dōrō}} ({{lang|ja|キリシタン灯籠}}, 'Christian lanterns'), did bear the "Lhq" [[monogram]], which, a quarter turned, was engraved on the shaft ({{transliteration|ja|sao}}), which was buried directly into the soil without basal platform ({{lang|ja|kiso}}). The [https://commons.wikimedia.org/wiki/File:Japanese_Rune_lhq_Japanese_Runic_Character.png 'Lhq'] monogram corresponds to the distorted letters 'IHS'.<ref>{{aut|JAANUS}} (2010) [https://www.aisf.or.jp/~jaanus/deta/o/oribedourou.htm ''oribe dourou'' 織部灯籠], Japanese Architecture and Art Net Users System</ref>
