Cassiopeia: Baby Name of the DayCassiopeia is a mythogloical moniker at home in the night sky, but rarely heard as a given name.

Thanks to Sarah C for suggesting our Baby Name of the Day.

Cassiopeia: The Queen

Back in the day, Cassiopeia reigned as queen. She and King Cepheus were the parents of the lovely Andromeda. Sounds like an ancient fairytale, right?

The queen was gorgeous and vain, and thought her daughter was every bit as gorgeous. She bragged – a lot – until one of her claims reached the ears of Poseidon. The queen, you see, declared that Andromeda was far more beautiful than the sea nymphs, and the sea nymphs? They were not pleased.

Poseidon set a sea monster on their kingdom, telling Cepheus that only the sacrifice of his daughter could save his realm.

That’s how Andromeda ended up chained to a rock on the coast, and if you’ve seen Clash of the Titans, you know the rest.

Poseidon was ticked that the hero Perseus managed to spirit away Andromeda, and so Cassiopeia was turned into a constellation and tucked away in the night sky.

There’s more than one woman by the name in Greek myth, but this story is the most famous by far.

Cassiopeia: Night Sky

Depending on the season, the constellation, and your spot on the Earth, Cassiopeia forms either an M or a W. The queen sits on her throne, perhaps chained there for eternity. Ptolemy listed the constellation way back in the second century, so it’s been around forever. The shape makes it easy to spot.

Parents love night sky names, from Luna to Stella, so this is a plus.

Sara Bareilles recorded a song about the constellation, and Rick Yancey’s The 5th Wave features a heroine named for the stars. Yancey’s Cassie is heroic, and might reform the name’s image with a younger generation.

Cassiopeia: By the Numbers

The original version of Clash of the Titans came out in 1981. Cassiopeia reached peak use in 1984. Credit goes to the movie, and to the popularity of Cassandra, too. But “peak” means a grand total of 15 girls – still very rare!

The 2010 movie remake could have given it a boost – but the queen’s boasting probably put some parents off.

In 2015, just eight girls received the name.

Other Cass- names have fared well in recent decades, including:

  • Cowgirl Cassidy, a late 1990s favorite
  • Nickname Cassie, which peaked in 1982, and was given to 191 girls last year
  • Nature name Cassia has never cracked the Top 1000, but was given to 61 girls in 2015

Other Cass- rarities include Casilda, a medieval Spanish saint’s name.

Cassiopeia: Wearable Rarity

So how do you pronounce Cassiopeia? I’ve always said it cass ee oh PAY uh, though I’ve heard others pronounce it cass ee oh PEE uh. I think that’s probably correct – and far less appealing, though a strong ‘p’ sound hasn’t held back Penelope.

Many parents adore long names for girls in 2016. Look at Top Ten favorites Olivia and Isabella. At five syllables, Cassiopeia tops them all.

Thanks to easy nickname option Cassie, this elaborate, dramatic name remains on the right side of wearable. If your heart is set on an extravagant rarity, Cassiopeia could be the name for you.

What do you think of Cassiopeia? Does the queen’s reputation bother you? Or is this name just plain too long?

  1. Ooh, I love Cassiopeia! Although, the myth of Queen Cassiopeia is indeed a little off-putting…I’d be more likely to use Andromeda.
    I’m honestly surprised J.K. Rowling didn’t name one of Sirius Black’s relatives Cassiopeia, since most of them do have astronomy names.

  2. My suggestion is name of the day? Yippee!

    Cassiopeia has been one of my favourite names for year. I immediately think of the Battlestar Galactica 1978 character when I hear it. For me, that makes up for the association with the mythological queen. I pronounce it Cass ee OH pee ah, which is how it is said on BSG. As for length, that’s part of what attracts me to the name. I would love to use it someday, probably with the nickname Cassie.

  3. I taught a young Cassiopeia one summer a few years back. Her mother is Irish and they pronounced it Cassie-oh-PEE-ah. She mostly went by Cassie, told me she was named for the constellation, and seemed to like her unusual name. Had I not met her, I would have thought it was a long and cumbersome name, but she proved me wrong. I think it’s lovely, and if I were to ever use it, I think I would use the nickname Cas.
