The modern celebration of Halloween is derived from the ancient festival of the dead, known in Ireland as Samhain. It is from Ireland that most of the Halloween traditions we have are inherited, through the Irish diaspora. Delving into the ancient past, this book uncovers the history of this festival in Britain and Ireland, including the forgotten goddess Tlachtga and the sacred temple of the Druids in County Meath, Ireland, where the first Halloween fires were lit.
