halcyon
"Halcyon" describes a period of time that is idyllically happy, peaceful, and prosperous. The word originates from a Greek myth about a bird that calmed the rough winter seas to build its nest, creating a tranquil atmosphere; thus, it evokes a sense of serene, golden calm. In modern usage, it is almost exclusively used to look back on a past era with nostalgia. You will most commonly hear it in the phrase "halcyon days," referring to a time in one's youth or a specific period in history when everything seemed perfect and untroubled.
