Take your dragon out for a fly. This is an early modern advice (from Athanasius Kircher), on how to and when to use your private #dragon to make an impression.
The image is part of his 1678 "Mundus Subterraneus" (access: https://www.digitale-sammlungen.de/de/view/bsb10806648?page=557 ), and describes the way of using a dragon by Jesuit missionaries to impress Non-Christians. When you zoom in, you see that the dragon features the Latin "Ira Dei": the wrath of God.
