octad etymology

Etymology

The word "octad" is derived from the Late Latin "octadis," which in turn comes from the Greek "oktas" or "ὀκτάς." This Greek word is related to "oktō" (ὀκτώ), meaning "eight."

Meaning

An octad is a group or set of eight. It can also refer to the eighth day after a specific event, such as a birth or a holiday.

Origin

The concept of an octad as a set of eight has its roots in ancient Greek mathematics and philosophy. The Pythagorean school, founded by Pythagoras in the 6th century BCE, placed great importance on the number eight, which they saw as a symbol of completeness and perfection.

The octad was also significant in ancient Chinese philosophy. In the I Ching, an ancient Chinese divination text, the eighth trigram, named "Pi," represents the idea of reunion or gathering together.

Over time, the word "octad" has been used in various contexts, including mathematics, music, and religion. In modern usage, it primarily refers to a set of eight elements or objects.
