Secrets of the Lost Races. New Discoveries of Advanced Technology in Ancient Civilisation

London: New English Library, 1980. - 205 c. На английском языке. Первое издание вышло в 1977. Книга поднимает некоторые труднообьяснимые факты использования древними цивилизациями некоторых продвинутых технологий. An increasing number of historical and archaeological finds made around the world have been classified as "out-of-place artifacts" (ooparts). They have been called this because they appear unexpectedly among the ruins of the past with no evidence of a preceding period of development; their technological sophistication seems far beyond the capabilities of ancient peoples.
