The Antikythera mechanism. Salvaged from an ancient shipwreck c. 1900. Ignored for years but then x-reayed to discover it was full of cogs despite being 2000 years old - 1700 years before the 'first' metal cogs were used. A reconstruction of the box showed that it tracked the motions of the stars and planets, with incredible accuracy. It was inscribed with text that has been 95% deciphered, but this translation has never been released.
a "glitch"... riiiiiight...

Technological artifacts of similar complexity and workmanship did not reappear until the 14th century, when mechanical astronomical clocks were built in Europe. modern reconstruction at…
