Artifex Pereo The Lantern And The Firefly Lyrics

I have a lantern. I turned it into a rocket for the sky, illuminating the ground in which I play. But my mother told me to put it away, led me to my room and made me a bed to lay. I have a firefly, tied to a string. I led into the sky. Casting out silver light onto the beds in which we slumber. But my mother told me to put it away. I killed the firefly, I lead him into the lantern in the sky. Oh mother what have I done?
