Definition
Relating to or determined by the rising or setting of a star at the same time as the sun; marked by the first visible appearance of a celestial body before sunrise.
Etymology
From Greek 'heliacos' (of the sun) combined with '-al,' a suffix forming adjectives. The term is fundamental to ancient and classical astronomy, particularly in Egyptian and Greek systems.
Kelly Says
The heliacal rising of Sirius was so important to ancient Egypt that they literally built their entire calendar around when this star appeared at dawn—it predicted the Nile floods that fed the entire civilization!
