Later, when I saw pictures of the ancient Egyptian falcon-headed god Horus, all faience and turquoise and with a perfect moustachial stripe below his wide, haunting eyes, I was stricken with a strange religious awe. This was my god, not the one we prayed to at school: he was an old man with a white beard and drapes. For weeks, in secret heresy, I whispered Dear Horus instead of Our Father when we recited the Lord’s Prayer at school assemblies.
