Mythology Names I'd Actually Use

I love so many mythological names but some of them are far too wacky to grace (or rather burden) a child with, so they are relegated to the potential pet list. These myth names and names relating to myths and legends are ones that I've found and would actually consider using. The list will probably be added to regularly as I come across more and more beautiful names. Currently, most are from Greek mythology (because I have studied Greek myth the most), but there are some from Roman mythology and a couple from Norse mythology and Arthurian legends. 

This highly unusual name -- the Halycyone was a mythic bird who could calm the seas -- conjures up images of utter peace and tranquility because of the phrase "Halycon days"...and the sleeping pill.

Like Violet, Lavender and Lilac, Ianthe is a purple flower name. Chosen by the poet Shelley for his daughter, Ianthe has a poetic, romantic, almost ethereal quality. In the ancient myth, she was the daughter of Oceanus, supreme ruler of the sea, and also a Cretan woman so beautiful that when she died the Gods made purple flowers grow around her grave.
 Iantha is also used.
 Ianthe was a favorite of the pastoral poets of the seventeenth century and then again in the early nineteenth. She appears in the works of Shelley, Barbara Pym and Georgette Heyer. Writer Richard Brautigan named his daughter Ianthe.

The meaning of this ancient Roman god's name relates to transitions, hence its connection to the name of the first month of the new year, a time of fresh beginnings. Janus is usually depicted as a two-faced god facing in opposite directions, since he looks both to the future and the past. It's no surprise then, that Janus is one of the premiere <a href="https://nameberry.com/list/629/71-wonderful-names-for-january-babies">January baby names</a>. The Slavic form Janusz is more commonly used than the English, represented by the Polish cinematographer Janusz Kaminski, who has shot all of Steven Spielberg's films from Schindler's List to Lincoln.

 But with January having been taken over by the girls, why not consider Janus? One caveat: it does sound a lot like the female Janice.
