Gaelic Type

Medieval inspired typefaces still found around Ireland as throwbacks to the past.

Gaelic type, also known as Irish type, or cló Gaelach in Irish, are typefaces inspired by the handwritten insular scripts of medieval Ireland. Insular scripts and insular art are works from Ireland and Great Britain (“insular” coming from the Latin “insula” meaning “island”). This medieval style spread from Ireland and Britain to Europe by way of Irish missionaries.

You can see both Insular scripts and insular art in the illuminated manuscripts of the time, with the 9th century Book of Kells being perhaps the most famous.

The Book of Kells is an excellent example of both insular script and insular art.
Gaelic type
Gaelic type was designed after medieval Irish insular script with a few letter forms be distinctly different from their Roman counterparts.

Insular script to Gaelic type

Invented in 7th century Ireland, insular scripts’ predecessors were uncial script (an all capitals style of writing) and half-uncial (a mix of capitals and lower case letter forms). What set insular apart was that its rounded letter bows were often very wide & circular, while its ascenders ended in triangular shapes. The letters “G” “D” and “T” are also markedly different from their Roman counterparts.

By the 16th century typefaces were created of the insular script styles. In 1571 the first Gaelic typeface was used for the text of a catechism, commissioned by Queen Elizabeth I, in an attempt to convert Irish Catholics to Anglicanism.

Gaelic type signage
Gaelic type was in regular usage well into the 20th century. Today you can still find it in street signage, pubs, packaging, and more.

Middle ages to the middle of the 20th century

Long after most countries had moved on to Roman style typefaces, Ireland continued to use Gaelic typefaces into the 20th century. The use of Gaelic type helped reinforce the country’s unique culture and served as a subtle form of protest against the British. Bilingual street signs feature Gaelic type for the Irish name and a modern font for the English name. In Dublin the CLÓSCAPE Research Project looks to document, and hopefully preserve, these bilingual signs.

Today you can still find some bilingual signs around Ireland that feature Gaelic type. Product packaging, advertising, pub signage, and logos continue to use Gaelic type as a nod to the past with an appreciation of Irish culture.

Indiana Jones and the Letter “J”

The letter “J” was the last letter added to the alphabet and probably wouldn’t have been a part of the crusaders’ trap.

In Indiana Jones and the Last Crusade Indy has to retrieve the Holy Grail in order to stop the Nazis and save his father – a classic MacGuffin. Between him and the Grail however are a series of traps constructed by knights of the First Crusade. One of these traps is a floor with flat stones individually marked with various letters of the alphabet. He is “to proceed in the footsteps of the word” and only step on the floor stones that spell the name of God. The name of God in this case is Jehovah but Indy makes the mistake of stepping on the letter “J” whereby the floor crumbles. He then remembers that in the Latin alphabet the first letter in the name Jehovah is actually an “I”.

the last letter of the alphabet

Jehovah in Latin was originally spelled “Iehouah” with a capital “I” because the letter “J” hadn’t been invented yet. This also means that Jesus’s name wasn’t “Jesus” in his lifetime. In Hebrew he was Yeshua or Yehoshua, or in Aramaic he was Isho or Yeshu. For a long time the letter “J” was just a fancy way of writing the letter “I”. It wasn’t until 1524 that Italian grammarian Gian Giorgio Trissino proposed separating the two letter forms to become two separate letters with two separate sounds, and in so doing made the letter “J” the last letter added to our alphabet.

This raises a typographical problem with the film. The letter “J” is part of the trap but it didn’t become a part of the alphabet until after 1524, a few hundred years after the First Crusade which was from 1096-1099. So we have to conclude that either:

  • the knights didn’t build the trap for more than 400 years after the First Crusade, or …
  • every now and then the immortal knight of the Grail updates the trap to include new letter forms over the centuries to keep the trap up to date with the times, or …
  • the writers of Indiana Jones and the Last Crusade didn’t do much alphabet research and incredibly audiences were willing to overlook such a flagrant error.
