A 'Christogram' is a
monogram or combination of letters which forms an abbreviation for the name of
Jesus Christ, and is traditionally used as a
Christian symbol. Different types of Christograms are associated with the various traditions of
Christianity.
Eastern Orthodoxy
In
Eastern Orthodoxy, the most widely used Christogram is a four-letter abbreviation 'ICXC' — a traditional abbreviation of the
Greek words for "Jesus Christ" (i.e., the first and last letters of each of the words — written "IHCOYC XPICTOC" with a transliteration of the
lunate sigma common in medieval Greek as "C"). On Western Orthodox icons this christogram may be split: "IC" on the left of the image and "XC" on the right, most often with a bar above the letters (see
titlos), indicating that it was a sacred name. It is sometimes rendered as "ICXC NIKA", meaning "Jesus Christ Conquers."
"ICXC" may also be seen inscribed on the
Ichthys. In the traditional Orthodox
ikon of
Christ Pantokrator, Christ's right hand is shown in a pose that represents the letters IC, X and C.
Western Christianity

IHS on a gravestone
In the
Latin-speaking Christianity of medieval Western Europe (and so among Catholics and many
Protestants today), the most common Christogram is "IHS" or "IHC", derived from the first three letters of the
Greek name of Jesus, ''
iota-
eta-
sigma'' or . Here the Greek letter ''eta'' was transliterated as the letter ''
H'' in the Latin-speaking West (Greek ''eta'' and Latin-alphabet ''H'' had the same visual appearance and shared a common historical origin), while the Greek letter ''sigma'' was either transliterated as the Latin letter ''C'' (due to the visually-similar form of the lunate sigma), or as Latin ''S'' (since these letters of the two alphabets wrote the same sound). 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 ''Iesus Hominum Salvator'' ("Jesus, Savior of men", in Latin), or connected with
''In Hoc Signo''. Some uses have even been created for the English language, where "IHS" is interpreted as an abbreviation of "I Have Suffered" or "In His Service". Such interpretations are known as
backronyms.
One of the oldest Christograms is the 'Chi-Rho' or
Labarum☧. It consists of the superimposed Greek letters
Chi ; and
Rho , which are the first two letters of christ in Greek. Technically, the word ''labarum'' is Latin for a standard with a little flag hanging on it, used in the army. A Christogram was added to the flag as an image of the Greek letters Chi Rho, in the late Roman period. So ''Christogram'' and ''labarum'' are not originally synonyms.
The most commonly encountered Christogram in English-speaking countries in modern times is the X (or more accurately, Greek letter Chi) in the abbreviation ''
Xmas'' (for "Christmas"), which represents the first letter of the word ''Christ''.
