Lucio Russo (born 22 November 1944) is an Italian physicist, mathematician and historian of science. Born in Venice, he teaches at the Mathematics Department of the University of Rome Tor Vergata.

In the history of science, he has reconstructed some contributions of the Hellenistic astronomer Hipparchus, through the analysis of his surviving works, and the proof of heliocentrism attributed by Plutarch to Seleucus of Seleucia and studied the history of theories of tides, from the Hellenistic to modern age.

The Forgotten Revolution[edit]


In The Forgotten Revolution: How Science Was Born in 300 BC and Why It Had to Be Reborn (Italian: La rivoluzione dimenticata), Russo stresses the well-established fact that Hellenistic science reached heights not achieved by Classical age science[citation needed], and proposes that it went further than ordinarily thought. These results were lost with the Roman conquest and during the Middle Ages, because the scholars of that period did not have the capability to understand them.[citation needed] The legacy of Hellenistic science was one of the bases of the scientific revolution of the 16th century, as ancient texts started once again to be available in Europe.

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",[1] even psychological analysis. They may have even discovered the inverse square law of gravitation (Russo's argument on this point hinges on well-established, but seldom discussed, evidence). Hellenistic scientists, among whom Euclid, Archimedes, Eratosthenes, developed an axiomatic and deductive way of argumentation. When this way of argumentation was dropped, the ability to understand the results were lost as well.[citation needed] Thus Russo conjectures that the definitions of elementary geometric objects were introduced in Euclid's Elements by Heron of Alexandria, 400 years after the work was completed.[1] 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).

A second contribution of Russo's is the conclusion that:

the post-Renaissance scientific revolution of the seventeenth century was basically due to the conscious recovery of the Hellenistic science (not even to its full extent, reached only in the second half of the nineteenth century with Richard Dedekind's and Karl Weierstrass's isolation of the real number concept directly out of Euclid's definition of proportion).[1]

Critical reception[edit]

The Forgotten Revolution has received mixed reviews. While reviewers praise Russo's enthusiasm, many note that the author's conclusions outreach his sources.[2][3][4] Writing for Nature, Mott Greene says, "Is this vision true to the facts? A great deal of it is, yes, but not all, and certainly not the bit about the inverse-square law. Yet the effort to spin out the 'what if …?' is well worth it."[5]

Other works[edit]

L' America dimenticata[edit]

In L' America dimenticata[6] Lucio Russo puts forward the bold hypothesis that the American continent was known in ancient times, probably discovered by the Phoenicians or the Carthaginians. Besides Hipparchus likely knew the longitude of the Lesser Antilles, then known as Blessed Islands, with remarkable precision.[citation needed]

Russo notes paintings dating to the Roman period and representing American fruits (Ananas), and small Mesoamerican toys representing wheeled trucks, when the wheel had not been invented nor used in pre-Columbian times.[citation needed]

With the collapse of the Hellenistic world under the attacks of the Romans around the middle of the 2nd century BC (specifically, the destruction of Corinth and Carthage in 146 BC and the expulsion of the scientific elite from Alexandria in 145 BC), these geographic notions were lost.[citation needed] Later Ptolemy incorrectly[citation needed] 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[citation needed], Ptolemy made ends meet by erroneously enlarging the longitude of all know places, and shrinking the width of a degree of longitude (500 instead of 700 stadia).[citation needed]

With this correction Lucio Russo manages to pinpoint the position of the mythical Thule, reached in the 4th century BC by explorer Pytheas, on the coast of Greenland.[citation needed] In addition he sheds a new light on an obscure sentence of Pliny according to which Hipparchus would have enlarged the known ecumene by 26,000 stadia.[7]
