How Brian Boru and the Vikings Are Described
The writer of Cogad Gáedel re Gallaib uses many strong words. They describe Brian Boru and his Irish followers in a very positive way. They are shown as brave and good. The text often highlights their Christian faith and loyalty.
But on the other side of that battle were brave, valiant champions; soldierly, active, nimble, bold, full of courage, quick, doing great deeds, pompous, beautiful, aggressive, hot, strong, swelling, bright, fresh, never weary, terrible, valiant, victorious heroes and chieftains, and champions, and brave soldiers, the men of high deeds, and honour, and renown of Erinn...
The book says that Brian and his Dál gCais warriors were like Augustus and Alexander the Great. It even suggests Brian's son, Murchadh, was like Hector. Hector was a famous hero from ancient myths. Murchadh is praised for his faith, bravery, and generosity. The story uses ideas from old myths and the Bible to describe Murchadh. For example, it gives him strengths like Hercules and Samson. The original Irish text also uses a lot of alliteration. This means many words start with the same sound, making it sound powerful.
In contrast, the book describes the Vikings very negatively. It uses strong, harsh words to condemn them:
Now on the one side of that battle were the shouting, hateful, powerful, wrestling, valiant, active, fierce-moving, dangerous, nimble, violent, furious, unscrupulous, untamable, inexorable, unsteady, cruel, barbarous, frightful, sharp, ready, huge, prepared, cunning, warlike, poisonous, murderous, hostile Danars; bold, hard-hearted Danmarkians, surly, piratical foreigners, blue-green, pagan; without reverence, without veneration, without honour, without mercy, for God or for man.
By describing the Vikings so badly, the text makes the Irish and Brian seem even better. It creates a clear difference between the good Irish and the bad foreigners.
Why Was This Story Written?
The main reason for writing Cogad Gáedel re Gallaib was to praise Brian Boru. It wanted to show that his family, the Dál gCais, deserved to be the High Kings of Ireland. At the time the book was written, Brian's family (the Ua Briain sept) was trying hard to keep this important title.
The story was written when Muirchertach Ua Briain was ruling. It was meant to connect him to his famous ancestor, Brian Boru. It was like saying, "Our family is great because Brian Boru was great!"
Some parts of Cogad Gáedel re Gallaib are similar to an Icelandic story called Njáls saga. This saga was written much later, around 1280. Scholars are still discussing how these two stories might be connected.
The writer of Cogad Gáedel re Gallaib shows the Vikings as cruel and wild. It even suggests that the people of Dublin at the time were like their Viking ancestors. Some think the book was partly written to "put the Dubliners in their place."
Today, many experts see Cogad Gáedel re Gallaib as clever "propaganda." It uses a very grand and patriotic style. Even though it's a valuable source for learning about the Viking Age in Ireland, we can't be sure if everything in it is completely accurate.
