ΑΡΚΤΟΥΡΟΣ
Arcturus, the brightest star in the constellation Boötes, is known as the 'guardian of the bear' due to its proximity to Ursa Major. Its heliacal rising and setting marked critical seasons for ancient Greek agriculture and navigation, making it a vital celestial indicator. Its lexarithmos (1261) is associated with concepts of completeness and cosmic order.
REPORT ERRORDefinition
Arcturus (Ἀρκτοῦρος, ὁ) is the brightest star in the constellation Boötes and the fourth brightest in the night sky. Its name, meaning 'bear-guard' or 'guardian of the bear,' derives from the Greek words «ἄρκτος» (bear) and «οὖρος» (guard, watcher), indicating its position near Ursa Major (the Great Bear). This proximity was central to ancient Greek astronomy and mythology, as Arcturus appeared to 'guard' the bear as it revolved around the celestial north pole.
The significance of Arcturus extends beyond mere stellar identification. For the ancient Greeks, and notably as recorded by Hesiod in his «Ἔργα καὶ Ἡμέραι» (Works and Days), the rising and setting of Arcturus were critical reference points for determining agricultural tasks. Its heliacal rising, i.e., its first appearance on the eastern horizon just before the sun, signaled the season for plowing and sowing, while its setting was associated with the grape harvest and other summer labors.
Beyond agriculture, Arcturus was also important for navigation, providing a reliable reference point for sailors traversing the Aegean and Mediterranean. Its consistent presence in the northern sky, in relation to the circumpolar Ursa Major, made it a celestial guide. Its mythological connection to Boötes, the 'Herdsman' or 'Ploughman,' further reinforced its role as a protector and guide, both of flocks and human endeavors.
Etymology
From the root «ἄρκτος» derive words such as «ἀρκτικός» (arctic, northern), «ἄρκτειος» (of a bear), and «ἀρκτοφύλαξ» (bear-guard, Boötes). From the root of «οὖρος» (from ὁράω) come words like «φρουρός» (guard, sentinel) and «τηροῦμαι» (to watch over, guard), underscoring the concept of vigilance and guardianship inherent in the star's name.

Word Family
