Ogham inscription is like a secret code that was used by people in Ireland a long, long time ago to write down messages using special symbols. Each symbol stands for a different letter of the alphabet, so if you know what the symbols mean, you can read the message!
The Ogham alphabet is a little different than the alphabet we use today. Instead of letters like A, B, and C, they had symbols that looked like straight lines, slashes, and dots.
People would carve these symbols into stone or wood, or sometimes they would write them on pieces of metal or bone. The inscriptions were often short and mysterious, and historians have spent a lot of time trying to figure out what they mean!
Today, Ogham inscription is considered an important part of Irish history and heritage. People still study it and try to figure out what messages and stories the ancient symbols might be telling us.
