Ὀγδόη Ἱσταμένου, VIII day
From today’s sunset: eighth day of Boedromion.
The eighth day is always sacred to Poseidon and Theseus.
“Poseidon Asphaleios stands for the ogdoad.”
“The eighth and the ninth of the month that begins: these are the best days to accomplish the man’s works: (Hesiod) praises the eighth and ninth plausibly as they carry perfection (syntelestikai) and therefore he has dedicated them to the human activities…one (the eight), by having a perfect dimension, the other (the nine), by deriving from a perfect number (the three), bring to accomplishment the works undertaken in them.”
Schol. Erga, 772-773
