As for the stories, they are pure enchantment. Focusing mainly on Irish myths, Rolleston takes us into the myths of the Irish invasion and the early Milesian kings. You’ll meet Queen Maev, Cuchulain the Giant, King Arthur and his knights (including the Grail quest) and much more.
In the Waldorf curriculum, these stories will fit nicely into the history and literature of the 6th grade. Outside Waldorf schools, I would recommend them for anyone 12 or older.
