Many people know the goddess Macha as one of the three Morrigans, but they may not be aware of her complex mythology apart from her sisters'. Macha is the premier goddess of Ulster, a powerful being who appears across stories in different forms, from a primordial deity to a human queen, each story offering a piece of who she was and is. This book explores all her various appearances in the original texts, as well as the ways she shows up in modern fiction and neopaganism, while sharing methods that can be used to better understand and honour her.
