So, I am technically getting to this a little late, after an emergency here at the daycare. It's already early morning here, but I had this mostly finished so I just typed up the last bit and please forgive this being a few hours late. Anyway, I hope you enjoy.
Polyhymnia is a goddess in Greek (and later Roman) mythology, described as one of the nine muses. She is the daughter of Zeus and Mnemosyne and the only one of her sisters to not have any recorded children, at least, any that I can find. Polyhymnia is regarded as the Muse of Sacred Hymns and Sacred Poetry and according to some modern sources she has an association with pantomime, which at best can only be traced back to Ancient Rome and actually helped form understanding of Roman myths and legends. Polyhymnia is usually portrayed in a meditative states, holding a finger to her mouth and wearing a long cloak and veil.
The asteroid Polyhymnia was discovered by Jean Chacornac on the 28th of October, 1854 in Paris, France. The asteroid takes roughly 1,774 days to travel around the zodiac, spending roughly 148 days in each sign. There isn't much else information on the asteroid.
Within my own research into the asteroid, Polyhymnia can be used to represent the native’s hymn or religious poetry writing ability, propensity for religious music or hymns, experiences with pantomimes, and religious elements of their life. Remember to check the sign, house, degree, and any aspects Polyhymnia makes when interpreting this placement. You can also have a look at Polyhymnia’s persona chart if you feel confident enough.
