''The Forgotten Revolution''

In ''The Forgotten Revolution: How Science Was Born in 300 BC and Why It Had to Be Reborn'' (Italian: ''La rivoluzione dimenticata''), Russo promotes the belief that Hellenistic science in the period 320–144 BC reached heights not achieved by

According to Russo, Hellenistic scientists were not simply forerunners, but actually achieved scientific results of high importance, in the fields of "mathematics, solid and fluid mechanics, optics, astronomy, anatomy, physiology, scientific medicine,"Graffi, Sandro, review of ''La rivoluzione dimenticata'', ''Notices Amer.

, 400 years after the work was completed. More concretely, Russo shows how the theory of tides must have been well-developed in Antiquity, because several pre-Newtonian sources relay various complementary parts of the theory without grasping their import or justification (getting the empirical facts wrong but the theory right). Hellenistic science was focused on the city of

. He also concludes that the 17th-century scientific revolution in Europe was due in large part to the recovery of Hellenistic science. ''The Forgotten Revolution'' has received mixed reviews, praising Russo's enthusiasm but noting that his conclusions outreach his sources.

incorrectly identified the Blessed Islands with the Canaries and since it was known that the Blessed Islands were at the antipodes relative to the eastern part of China, Ptolemy made ends meet by erroneously enlarging the longitude of all known places, and shrinking the width of a degree of longitude (500 instead of 700 stadia).
