Christogram - Western Christianity

Western Christianity

In the Latin-speaking Christianity of medieval Western Europe (and so among Catholics and many Protestants today), the most common Christogram became "IHS" or "IHC", denoting the first three letters of the Greek name of Jesus, iota-eta-sigma, or ΙΗΣ.

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 Iesus Hominum Salvator ("Jesus, Savior of men" in Latin) or connected with In Hoc Signo. Such interpretations are known as backronyms. Used in Latin since the seventh century, the first use of IHS in an English document dates from the fourteenth century, in The vision of William concerning Piers Plowman. 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). English-language interpretations of "IHS" have included "I Have Suffered" or "In His Service", or jocularly and facetiously "Jesus H. Christ".

One of the oldest Christograms is the Chi-Rho or Labarum. It consists of the superimposed Greek letters chi (Χ) and rho (Ρ), which are the first two letters of Christ in Greek. Technically, the word labarum is Latin for a type of vexillum, a military standard with a flag hanging from a horizontal crossbar. A Chi-Rho Christogram was added to the flag by the Emperor Constantine I in the late Roman period. Therefore Christogram and labarum were 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.
