IHS is one of the most widespread christograms in the Christian West. Originally, the three letters correspond to an abbreviation of the Greek name for Jesus, ΙΗΣΟΥΣ, transcribed in Latin characters. During the Middle Ages and the Renaissance, the sign receives new Latin interpretations and becomes a major devotional emblem. Bernardine of Siena contributes greatly to its dissemination in the 15th century by presenting the monogram in a radiant disk. In the 16th century, the Society of Jesus adopts it in turn and contributes to its worldwide dissemination.

Where do the three letters IHS come from?
The Metropolitan Museum of Art describes IHS as an abbreviated form of the Greek name for Jesus. The three letters refer to the first characters of ΙΗΣΟΥΣ when it is transcribed in the Latin alphabet.
The sign is therefore initially a condensed name. It belongs to the same family as the Chi-Rho, which abbreviates the Greek word Christos, but the two monograms are not constructed from the same term.
Medieval manuscripts and liturgical objects exploit the ability of abbreviated writing to become an image. The letters can be enlarged, surrounded by a circle, crowned with rays, or accompanied by a cross.
Why does the radiant monogram become famous?
In the 15th century, Bernardine of Siena develops a form of preaching centered on the Holy Name of Jesus. He presents the IHS monogram in a radiant disk that he shows to crowds during his sermons.
The Met preserves several works in which Bernardine holds this disk as his principal attribute. The image becomes so characteristic that it makes it possible to identify the saint in Italian art.
Its growing prominence transforms the name into a luminous presence. The monogram is no longer a simple calligraphic abbreviation: it becomes a visible emblem of public devotion.
How does the Society of Jesus adopt it?
The Society of Jesus, founded in the 16th century, adopted IHS as a central element of its emblem. The sign may be accompanied by a cross placed on the bar of the H, three nails, and a radiant sun.
The Metropolitan Museum preserves Chinese porcelain pieces intended for the Portuguese market on which the IHS monogram appears even before or around the beginnings of the Society. The museum specifies that the Jesuits would later adopt it as a symbol of their order.
This history reminds us that the Jesuits did not create IHS. They adopted an already ancient Christogram and gave it additional worldwide circulation.
What are the Latin expansions of the acronym worth?
Latin phrases such as Iesus Hominum Salvator, “Jesus, Savior of Humanity,” have been used to explain IHS. They are theologically coherent and well attested in the symbol’s reception.
However, they do not constitute the linguistic origin of the three letters. The starting point is the abbreviated Greek name of Jesus.
This distinction is important for “Grimoire of Symbols”: an interpretation can be ancient and legitimate without being the sign’s original etymology.
Where can IHS be found in Christian iconography?
IHS appears on chasubles, chalices, altarpieces, church façades, ceramics, manuscripts, and personal objects. Its compactness allows it to become a true visual seal.
An 18th-century Portuguese chasuble preserved at the Met associates IHS with the phoenix, the rose, the pelican, and the pomegranate. The monogram thus becomes part of a comprehensive program of Christian symbols.
The Alpha and Omega pair and IHS show two different ways of transforming letters into emblems: one expresses beginning and end, while the other directly names Jesus.
