halcyon days

A period of calm, usually in the past and often nostalgic.

From Latin *Alcyone*, from Ancient Greek *Ἀλκυόνη* (*Alkuónē*), the term originates in the domestic arrangements of the daughter of Aeolus. Following the death of her husband Ceyx in a shipwreck, Alcyone threw herself into the sea, an act of grief that prompted the gods to transform the couple into kingfishers. The birds, subsequently known as halcyons, encountered a logistical difficulty when Alcyone attempted to nest upon the beach, as the waves threatened the security of her eggs.

To facilitate the nesting process, Aeolus restrained his winds for seven days each year, ensuring the sea remained calm while Alcyone tended to her nest. These seven days of enforced meteorological stillness became known as the halcyon days, a period defined by the reliable absence of storms. The term persists in English as a reference to a past era of happiness or success, long after the birds and the intervention of Aeolus have ceased to be a primary concern of the maritime authorities.
