Ancient crypto stick

In cryptography, a scytale (rhymes approximately with Italy; also transliterated skytale, Greek σκυτάλη "baton") is a tool used to perform a transposition cipher, consisting of a cylinder with a strip of parchment wound around it on which is written a message. The ancient Greeks, and the Spartans in particular, are said to have used this cipher to communicate during military campaigns.
The recipient uses a rod of the same diameter on which the parchment is wrapped to read the message. It has the advantage of being fast and not prone to mistakes—a necessary property when on the battlefield. It can, however, be easily broken. Since the strip of parchment hints strongly at the method, the cipher text would have to be transferred to something less suggestive, somewhat reducing the advantage noted.

Temple of Aphaea

The Temple of Aphaia (Greek: Ναός Αφαίας) or Afea is located within a sanctuary complex dedicated to the goddess Aphaia on the Greek island of Aigina, which lies in the Saronic Gulf. Formerly known as the Temple of Jupiter Panhellenius, the great Doric temple is now recognized as dedicated to the mother-goddess Aphaia. It was a favorite of the neoclassical and romantic artists such as J. M. W. Turner. It stands on a c. 160 m peak on the eastern side of the island approximately 13 km east by road from the main port.

Lucian True History

A True History or A True Story (Ancient Greek: Ἀληθῆ διηγήματα, Alēthē diēgēmata; Latin: Vera Historia) is a parody of travel tales, by the Greek-speaking Assyrian author Lucian of Samosata, the earliest known fiction about travelling to outer space, alien life-forms and interplanetary warfare. Written in the 2nd century, the novel has been referred to as "the first known text that could be called science fiction". The work was intended by Lucian as a satire against contemporary and ancient sources, which quote fantastic and mythical events as truth.
