The article examines the two different genealogies of the Emmenids reported by the scholia on Pindar's Olympian 2: scholl. 16c ~ 70f Dr. connect Theron to the Labdacids Thersander and Polynices via Thera (the ‘Therean’ genealogy), whereas 82d Dr. links him with Eteocles via Rhodes (the ‘Rhodian’ genealogy). Modern interpretations associate the former with the Epinician, the latter with the Encomium to Theron. By contrast, it is argued that the ‘Therean’ genealogy originated from an ancient mistaken interpretation of the role of Thersander in Ol. 2.43–7: a careful reading of that passage and of relevant testimonia shows that Pindar endorsed the ‘Rhodian’ version in both poems, thus showing a unanimous tradition.
