Strabo vs. Posidonius: polemics over Solar influence on the climate in F 223 EK

Posidonius' F 223 EK has been long regarded a puzzle. In this text Strabo discusses a theory of Posidonius about the influence of the Sun on the climate. The article argues that Strabo misinterprets Posidonius' words and ascribes him egregiously absurd ideas. Accordingly, modern commentators, following Strabo, misconstrue Posidonius' theory in the same way. The article suggests a new interpretation of this theory, which makes it possible to explain Posidonius' words and save him from false charges of absurd ideas.
