I had no idea about this when I first got the idea for Goldenbird (I have to thank Irish poet W.B. Yeats for that), but according to The Oneirocriticon of Daniel from the fourth century AD (a.k.a. The Dreambook of the Holy Prophet Daniel with the Help of Holy God, according to the Alphabet): “Dreaming of birds made of gold or silver signifies an untimely quarrel.”
