Pyrseia (Fire Signals) - a communication and data encryption system
The representation is based mainly on the text of the historian Polybius (History X), who states that it was invented by the Alexandrian engineers Cleoxenus and Democleitus, and improved it himself. Information also exists in renaissance depictions.
It was based on the division of the letters of the Greek alphabet into groups of five lines and five columns. Double towers were used to transmit the messages, each of which could support five torches. The left torches represented the position of the letter in the rows and the right torches in the columns. They could be seen over long distances with the help of binoculars. It is the first coding of the alphabet. The next one was made after 20 centuries by S. Morse. It can be considered a forerunner of digital technology.
