Arktos was a centaur who fought against the Lapith spearmen.[1]

Arktos is also one of the The Hours, known as Horai - Greek tutelary goddesses of the time of day; Arktos is last light.[2]

"The hall of Allmother Harmonia [in the vault of heaven], where that Nymphe dwelt in a house, self-built, shaped like the great universe with its four quarters joined in one. Four portals were about that stronghold standing proof against he four Aetai (Winds). Handmaids [Horai of the Hours] protected this dwelling on all sides, a round image of the universe: the doors were allotted - Anatolia (Rising) was the maid who attended the East Wind’s (Euros’) gate; at the West Wind’s (Zephyros’) was Dysis (Setting) the nurse of Selene; Mesembrias (Midday) held the bold of the fiery South (Notos); Arktos the Bear was the servant who opened the gate of the North (Boreas), thick with clouds and sprinkled with hail."[3]
