From the transcript
Have you ever imagined how soldiers communicated during the deafening noise of a fierce battle? Throughout history, armies have relied on a fascinating array of signaling devices to transmit messages, and one of the most intriguing examples is the ancient Greek hydraulic semaphore.
The ingenious communication system developed in the 3rd century BCE by the engineer Anius Tacitus used water to transmit messages over long distances.
The hydraulic semaphore consisted of two identical containers filled with water, connected by a long tube. Each container had a rod with various symbols or letters inscribed in it. To send a message, the sender would raise the rod in their container to the desired symbol, causing the water level to drop.
