Livio Catullo Stecchini (1913-1979) was an Italian science historian with a special interest in ancient metrology and cartography. In an unpublished work called Sahara, he advocated São Tomé, in the Gulf of Guinea, as the location of Atlantis. He further claims that the myth of the Argonauts concerns their travels along the vast river systems that once existed across the Sahara, now represented by dried-up watercourses such as Wadi Igharghar and Wadi Tafanasset.
Stecchini was of the opinion that the metric system introduced in the 18th century by the French was almost identical to that used in Mesopotamia in the 3rd millennium BC.
His radical views eventually led this respected academic to be shunned by his peers.
A site dedicated to his work is available on the Internet(a).
>Stecchini was an important contributor to a special edition of American Behavioral Scientist dedicated to the work of Immanuel Velikovsky in September 1963. This was later expanded into The Velikovsky Affair  by Alfred De Grazia.(b)<
