When you read a book, it's like you're going on an adventure in your imagination. Sometimes, the words in the book are written in a different language, like Welsh. Wales is a country with its own language, Welsh, which has been spoken there for a really long time.
The literature of Wales refers to all of the stories, poems, and plays that have been written in Welsh. These stories and poems have been passed down from generation to generation, almost like a game of telephone. People would tell the stories to their children, who would tell them to their children, and so on. Eventually, they were written down so that they wouldn't be lost forever.
One of the most famous Welsh stories is the tale of King Arthur and his knights. Many people believe that King Arthur was a real person who lived a long time ago, but we don't know for sure. Either way, his story has been told and retold in many different ways over the years, and it's still a popular story today.
Another famous Welsh writer is Dylan Thomas. He wrote a lot of poetry and plays in English, but he also wrote some things in Welsh. His most famous works are probably his poems, which are known for their beautiful language and imagery. Some of his most famous poems include "Do not go gentle into that good night" and "And death shall have no dominion".
Overall, the literature of Wales includes a lot of different stories and poems that have been passed down from generation to generation. Some of the stories are about real people, like King Arthur, while others are completely made up. But they all have one thing in common - they are an important part of Welsh culture and history.
