Can I use the term halcyon to mean calm or tranquil when describing something other than a period of time, especially a place or setting?

For example, does the following sentence seems unnatural or contrived?

He walked through the halcyon temple, admiring the aging frescoes.

All dictionaries cite phrases like, "the halcyon days of summer" or "the halcyon years", but a few other sources which use it in other ways—often as proper names or when describing a tree kingfisher, genus Halcyon, but occasionally as a general purpose adjective. Still, I'm not sure how 'proper' this use is or if it has some kind of subtle connotation I'm not aware of.

  • Interestingly enough, Deerhunter has an album named Halcyon Digest. I'm not quite sure what they mean by it, but it sounds cool.

The adjective halcyon is hard to use outside of the phrase halcyon days, and the reason has to do with its origin and development.

A halcyon is a sort of bird which we nowadays call a kingfisher.¹ The halcyon was supposed to have built a nest on or near the sea, and to have incubated her eggs during the relatively peaceful weather surrounding the winter solstice.

The Greeks explained this midwinter period of calm by saying that the body of Ceyx, a young demigod, floated to shore after his ship was destroyed in a midwinter storm. He was found by his lover, Alcyone, daughter of Aeolus, the god of winds. Overwhelmed by grief, she drowned herself in the sea. The gods took pity on the couple and reunited them, transforming them into kingfishers. Aeolus quieted the winds every year to protect his daughter’s nest.²

So, since antiquity, the phrase halcyon days has literally meant this nesting period of about two weeks of calm weather surrounding the winter solstice.³ The phrase has also come to be used as a metaphor meaning any calm, peaceful, or fruitful moment between difficulties. And out of it, in a sort of back formation, halcyon has transformed again, this time from a bird (a noun adjunct in the phrase halcyon days) into a separable adjective meaning “calm” or “peaceful”. But the transformation is incomplete. Halcyon (adj.) still pairs mostly with words for time or space: for example, “days”, “years”, “air”, or “atmosphere”.

Poetically speaking, the affinity between halcyon and time and space words is apt because of Ceyx’s family connections. The travels of his father Eosphorus through space marked the passage of time and the seasons. Eosphorus was the “dawnbringer”, “lightbringer”, or “daystar”, known today as Venus rising. His particular brightness before sunrise during the halcyon days presaged the weakening of winter and the return of longer days and fruitful weather.

  • So how does it sound in my example sentence? Would you suggest I avoid using it except in those combinations?

    @p.s.w.g That's more of a matter of opinion or request for writing advice. I'm happy to oblige, but as it is strictly opinion I am not including it in the answer. 1. Consider your reader above everything else. 2. Your reader who understands "halcyon days" may be surprised by "halcyon temple". Your reader who doesn't will be sent running to the dictionary. Either outcome disrupts the flow of words. 3. You are likely to get better writing advice at Writing.

  • Thanks, that answers my concern about whether this kind of usage seems unnatural.

The adjective form of halcyon is synonymous with serene ("pleasingly or idyllically calm or peaceful" per M-W), so you could certainly use it in that sense.

However, I'd use halcyon to describe a part of the temple, since it's too easy read your sentence as being set in a Temple of Halcyon.

He walked through the temple's halcyon nave, admiring the ageing frescoes.

  • Yes, I was wondering about exactly this, since halcyon might be interpreted as a name or some kind of bird-god.

Halcyon days is a set phrase.

It is not correct to presume that the word halcyon by itself means 'calm' or 'tranquil' thereby modifying 'days'.

1540s, in halcyon dayes (Latin alcyonei dies, Greek alkyonides hemerai), 14 days of calm weather at the winter solstice, when a mythical bird (identified with the kingfisher) was said to breed in a nest floating on calm seas. [Halcyon is] identified in mythology with Halcyone, daughter of Aeolus, who when widowed threw herself into the sea and became a kingfisher. (etymonline)

Yes, You can use it as a general adjective to describe something other than time. For example: 'A halcyon atmosphere'.


Yes, halcyon can be used as an adjective for subjects other than times. However, I find it jarring in the example sentence. Of its synonyms calm, undisturbed, peaceful, serene, blissful, relaxed, I would have no trouble with undisturbed or peaceful as modifiers of temple; but the others seem jarring to me because I find them more suggestive of a frame of mind than of a particular atmosphere, and temples don't have minds. But one could say “He walked through the temple, admiring the aging frescoes in the halcyon air” or “He walked through the temple's halcyon rooms, admiring the aging frescoes”, etc.

  • Interesting. So when not applied to periods of, halcyon implies mindfulness? Or is that just something particular to this case?

  • @p.s.w.g, some of the synonyms imply mindfulness. Halcyon does not (eg, halcyon breeze is a common phrase) but I don't have a better explanation than mindfulness for why I find halcyon temple jarring. Commented Jul 30, 2013 at 16:17
