2. Metageitnion (Aug.-Sept.).
3. Boëdromion (Sept.-Oct.).
4. Pyanepsion (Oct.-Nov.).
5. Mæmacterion (Nov.-Dec.).
6. Poseideon (Dec.-Jan.).
7. Gamelion (Jan.-Feb.).
8. Anthesterion (Feb.-Mar.).
9. Elaphebolion (Mar.-Apr.).
10. Munychion (Apr.-May).
11. Thargelion (May-June).
12. Scirophorion (June-July). A fixed relation to the seasons was maintained by introducing an intercalary month, “the second Poseideon, ” at first in an inexact way, afterward in years 3, 5, 8, 11, 13, 16, 19 of the Metonic cycle. Dates were reckoned in Olympiads. [ Webster 1913 Suppl. ]
