Nest, home, local habitation, it has none; like the Scythians, it elects to lead a wandering life, and where night finds it, there is its hearth and its chamber. But as I said, it works no deeds of darkness; ‘live openly’ is its motto; its principle is to do no villany that, done in the face of day, would dishonour it.

Legend tells how Myia (the fly’s ancient name) was once a maiden, exceeding fair, but over-given to talk and chatter and song, Selene’s rival for the love of Endymion. When the young man slept, she was for ever waking him with her gossip and tunes and merriment, till he lost patience, and Selene in wrath turned her to what she now is. And therefore it is that she still, in memory of Endymion, grudges all sleepers their rest, and most of all the young and tender. Her very bite and bloodthirst tell not of savagery, but of love and human kindness; she is but enjoying mankind as she may, and sipping beauty.
