The '''[[Antikythera mechanism]]''' ({{IPAc-en|ˌ|æ|n|t|ɨᵻ|k|ɨᵻ|ˈ|θ|ɪər|ə}} {{Respell|ANT|i-ki|THEER|ə}} or {{IPAc-en|ˌ|æ|n|t|ɨᵻ|ˈ|k|ɪ|θ|ərə|r|ə}} {{Respell|ANT|i|KITH|ə-rə}}) is an ancient [[Analog computer|mechanical computer]] designed to calculate [[astronomy|astronomical]] positions. It was recovered in 1900–1901 from the [[Antikythera wreck]]. Its significance and complexity were not understood until decades later. Its time of construction is now estimated between 150 and 100 [[Before Christ|BC]]. Technological artifacts of similar complexity and workmanship did not reappear until the 14th century, when mechanical [[astronomical clock]]s were built in Europe.<noinclude>
