The Blueprint #
A full-page splash of the Steam Engine schematic as interpreted by Marcus. It looks like a piece of heavy artillery repurposed for industry: a vertical bronze cylinder mounted on a heavy timber frame with a large iron flywheel.
Marcus has included practical build notes in Latin: "Cast the cylinder in one pour. If a seam shows, melt it again. Test with cold water first. The relief plug must lift before the vessel cracks."
In the margins, his doubts linger: "A pot that pushes like a bull. Will they believe it? If this explodes, it will be my name on every widow's tongue. I serve the hungry. If fire must work for us, then we must teach it. Vulcan, forgive me. I borrow your breath."
