On dating Hero of Alexandria

  • Ramon MasiàEmail author

Abstract

The dating of Hero of Alexandria has been linked with the lunar eclipse of March 13, ad 62, since Otto Neugebauer discovered that this eclipse is the only one that can fit the one described in Hero’s Dioptra 35. Although only a number of scholars claim that Hero himself observed the eclipse, almost all of them take Neugebauer’s identification for granted. We use statistical and linguistic methods to criticize this assumption: all indices we have found point to the fact that the eclipse was merely invented as an example and, for that reason, that it cannot be used to determine Hero’s life span.

Notes

Acknowledgments

I am grateful to Bernard Vitrac for his insightful comments and remarks at every stage of elaboration, which improved the argument and avoided a serious mistake. Special thanks are given to Fabio Acerbi for critical scrutiny of the typescript and detailed remarks.
