St Patrick’s Day is celebrated by millions of people all around the world, but many of them know next to nothing about the saint they are commemorating. That is a pity because Patrick is not only a very interesting saint but a very interesting man. So let’s just take a brief look at what today is all about.

Unlike some very early saints about whom we know hardly anything – for example, there are at least two candidates who could be St Valentine – Ireland’s patron saint, St Patrick, is well established in history. We know a lot about him, or should do, partly from his own writings, which are still in print today.
