heliacal etymology

Etymology:

• Greek: "helios" (sun) + "akros" (tip, point)

Meaning:

• Relating to or occurring near sunrise or sunset, specifically when a star or planet is just barely visible at the horizon.

Origin:

The term "heliacal" was first used by ancient Greek astronomers to describe the first or last appearance of a star or planet in the sky at sunrise or sunset. This was an important observation for marking the seasons and for agricultural purposes.

• In ancient Greece, the heliacal rising of the star Sirius (the "Dog Star") was a significant event that marked the beginning of the summer season.
• Similarly, the heliacal setting of the star Arcturus marked the onset of autumn.

Over time, the term "heliacal" came to be used more generally to refer to any celestial object that is visible near the horizon at sunrise or sunset.
