The pantelegraph predated the telephone

In 1865, a commercial image transmission service began on the Paris–Lyon telegraph line using Giovanni Caselli’s pantelegraph, an early electromechanical facsimile device. This was about 11 years before Bell’s telephone demonstrations in 1876. A qualification: Caselli did not create the first facsimile device of any kind; experimental systems and public demonstrations came earlier. The Paris–Lyon commercial line was the milestone. [1–3]

Prompt: “Historically grounded editorial illustration of Giovanni Caselli's 1860s pantelegraph, an early electromechanical facsimile telegraph: tall wooden frame with pendulums, brass mechanisms and paper/tin scanning drums, Paris–Lyon telegraph wire suggested in background, museum engraving style, neutral sepia palette, no invented writing, no logos, explanatory educational art, clearly an illustration rather than a photograph.”
