Archaeology, a magazine published by the Archaeological Institute of America has released its list of the Top 10 discoveries of 2018, with two unexpected ancient Greek finds making the list.

The first hails from Olympia, specifically from a village near the ancient sanctuary of Zeus. A pile of unassuming discarded building material proved to conceal a precious ancient artifact – a plaque inscribed with a verse of the Odyssey. It is thought to be the oldest inscribed section ever discovered in Greece of the epic poem describing the adventures of Odysseus during his decade-long return to Ithaca following the Trojan War.

The poem is thought to have been composed in the 8th century BC and first written down in the 6th century BC, although the inscription itself dates to centuries later – around the third century AD, according to Archaeology magazine. The inscription recounts Odysseus’ arrival in Ithaca and his reunion with his trusted swineherd. One theory put forward is that it was originally commissioned by a landowner in the region and later re-purposed as building material.
