Data of Ancient Greek Parapegmata

In ancient Greece, calendrical lists of significant weather events are today called "parapegmata" (Graßhoff, Gerd 2017). They are aligned with the seasonal change of the sun's course and correlate the weather events with visible horizon phenomena of the rising and setting stars at dawn and twilight (Taub, Liba 2003). These so-called "heliacal risings and settings" of the brightest stars mark exactly a seasonally fixed day during the year when a particular star becomes visible near the horizon for the first or last time before a time of invisibility due to proximity to the sun. The heliacal rising and setting phenomena marked the seasonal calendars for early cultures.
