Author's note: Today scientists can explain the causes of lightning. We accept it as a natural phenomenon. Traditional Aboriginal people accepted it too, but like many people today they were cautious of it. There are Dreamtime legends form many areas about lightning and its sometimes terrible effects. The legends vary from place to place, but many of them agree in depicting lightning as an element of rage. This legend is from Arnhem Land, where the lightning has always been given human form. The lightning man was called Wala-Unayua.
