Today, Tenos is famous for being a beautiful island with windmills all over its landscape (over 80). In ancient times, the island was more known for its many springs and even more snakes. It was here that Herakles slayed the sons of Boreas.
During Xerxes invasion, the island sent a trireme in support of the Persians, then defected to the Greeks and were therefore honored. They also fought at the Battle of Platea.
For some time, the island was under the control of Alexander of Pherai.
With Theban power down after the death of Epaminondas, Alexander of Pherai takes Tinos and sells the inhabitants as slaves, then besieges Peparethos. Athens defeats Alexander near Sounion and relieves Peparethos. Alexander then plunders Piraios.
