A folklore book is an almost perfect pleasure. The stories in them always have a lot of variety (heroic? humorous? horror? they got it all!) so you will never get bored. They are often very short, so you can just pick it up and read it anytime. They always have a lot of historical and cultural information in them so you are learning more about the world, too. What could be better?
A lot of Icelandic folklore can also be found in Scottish Folklore and even Nova Scotian Folklore, proving that European people kept their oral traditions around for a very long time regardless of time and place. I find that amazing. Stories of fairies, saints, and magic have been entertaining European-descendent people for generations!
One will find in these stories that many themes in folktales have become popular tropes. I noticed this more with the Icelandic folklore that I have read in this book than with any other book. Trolls (giant ugly creatures who eat cattle and humans who turn into stone upon contact with sunlight - guess where Tolkien got the idea?) and Black Magic.
The introduction gives you a lot of trust in the accuracy of the book that you are reading. The folktales are full of useful footnotes, references, etc which are a real joy to see in a book like this because I am always afraid that when people compile folklore for books they might "spice them up" by adding details that weren't in the originals that appeal to or make sense to modern people. But I didn't feel like there was anything like that in these stories.
The stories are set up into different sections: ghosts, saints and sinners, etc. This gives them even more variety. I felt like this book showcased just enough of each topic, unlike so many other folklore books that often get repetitive when they showcase stories with the same theme over and over and over again.
The only thing I didn't like in these stories are the illustrations. The illustrations are apparently done by a great Icelandic artist, but I didn't like them. I feel like illustrations in a book like this should acquaint you with the traditions of visual artistry in these regions which, when paired up with the folktales, should help you become absorbed in the culture. But the illustrations in this book were often confusing, and looked like something out of a Frank Miller graphic novel (seriously, they were WEIRD). They often took me OUT of the stories, when they should be having the opposite effect. I looked at some traditional icelandic art online to see what it was like, and it was quite different from the illustrations in the book. Often the illustrations would be nothing at all like how I imagined the scene. Seriously, if the illustrations weren't in this book I would give it a higher rating.
The illustrations in "Great Folk Tales of Old Ireland" are a great example of what illustrations should be in a book like this. They look "archaic", they stimulate the imagination, they create atmosphere. This book deserves illustrations like the ones in that book.
Overall, a great book that I recommend to anyone interested in learning about foreign cultures or who loves European folklore (like me!).
