Egyptian hieroglyphs were a formal writing system used by the ancient Egyptians that combined logographic andalphabetic elements. Egyptians used cursive hieroglyphs for religious literature on papyrus and wood. Less formal variations of the script, called hieratic and demotic, are technically not hieroglyphs.

5.Greek Hydraulic telegraph- Greece- 4th Century BC
A hydraulic telegraph was one of two hydraulic-telegraphic telecommunication systems, one developed in 4th century BC Greece, and the other in 19th century AD Britain. The Greek system was deployed in combination with semaphoric fires, while the latter British system was purely hydraulic.
Although both systems employed water in their sending and receiver devices, their transmission media were completely different. The ancient Greek system transmitted its semaphoric information to the receiver visually, which limited its use to line-of-sight distances in good visibility weather conditions only.

A carrier pigeon is a homing pigeon (specifically a domesticated rock pigeon, Columba livia) that is used to carry messages. Using pigeons to carry messages is generally called "pigeon post". Most homing or racing type varieties are used to carry messages. There is no specific breed actually called "carrier pigeon". Carrier pigeons that are the basic Racing Homer were used to carry messages in World War I and World War II. Thirty-two pigeons were presented with the Dickin Medal.
