Subject/Title of Window: IHC/Shield of the Trinity/Sign of the Fish

Brief Description of Subject: This clerestory window is located in the sanctuary and features 3 large roundels, with symbols, alternating with three smaller roundels.

The larger roundels from top to bottom:
IHC. The New Testament is written in Koine Greek, so that the earliest symbols have their basis in the Greek language. The Greek spelling of their word for "Jesus" is "iota eta sigma upsilon sigma." Transliterated into the Latin alphabet this becomes "IHCOYS." Thus the first three letters, "IHC," form a Christogram for "Jesus."
Shield of the Trinity. Also known as "Scutum Fidei" (Shield of Faith), it originated in the 13th Century as a visual aid in understanding the triune nature of God. Pater (Father), Filius (Son) and Spiritus Sanctus (Holy Spirit) are each separate but is one God (Deus). Note "EST" (is) and "NON EST" (is not).
Sign of the Fish. This roundel was installed backwards. Looking in a mirror the Greek letters spell out "IXOYC." Transliterated into the Latin alphabet, this becomes "ICHTHYS," the Greek word for "fish." These letters form an acronym for (I)esous (CH)ristos (TH)eou (Y)ios (S)oter --- "Jesus Christ, Son of God, Savior" --- the core belief of the Christian faith.

The MSGC is a constantly evolving database. Not all the data that has been collected by volunteers has been sorted and entered. Not every building has been completely documented.

All images in the Index are either born-digital photographs of windows or buildings or are scans of slides, prints, or other published sources. These images have been provided by volunteers and the quality of the material varies widely.

If you have any questions, additions or corrections, or think you can provide better images and are willing to share them, please contact
