ΟΡΘΡΟΣ
Orthros, the hour of dawn, the first appearance of light, is a word that connects the natural world with the mythological. As the time when the sun "rises erect," it symbolizes beginning, vigilance, and revelation. In Greek mythology, Orthros is also the fearsome, two-headed dog of Geryon, son of Typhon and Echidna, brother of Cerberus, who guarded Geryon's cattle and was slain by Heracles. Its lexarithmos (549) reflects the complexity and power of both sunrise and guardianship.
REPORT ERRORDefinition
According to the Liddell-Scott-Jones Lexicon, ὄρθρος primarily denotes "the time just before sunrise, the early morning, dawn." It is the hour when light begins to dispel darkness, marking the beginning of the day and the awakening of nature and humanity. The word is used extensively in ancient Greek literature to describe this crucial transitional period.
Beyond its temporal meaning, Ὄρθρος also acquired a significant mythological dimension. He was the two-headed dog of Geryon, a three-bodied giant whom Heracles was tasked to kill as part of his labors. Orthros, son of the monsters Typhon and Echidna, and brother of Cerberus, was the guardian of Geryon's herds on Erytheia, and was slain by Heracles before the hero confronted Geryon himself.
This dual nature of the word—as a temporal concept and as a mythological entity—makes it particularly rich. In Christian worship, Orthros is also the name of the Matins service, performed in the early morning hours before the Divine Liturgy, maintaining the connection to dawn and spiritual awakening.
Etymology
From the same root, many words are formed that describe the time of dawn or the act of early rising. Examples include the verb ὀρθρεύω ("to rise early, to be out at dawn"), the adjective ὀρθρινός ("of the early morning, matutinal"), and the adverb ὀρθρόθεν ("from early morning"). All these words retain the basic meaning of sunrise and vigilance.
