In 2023 scientists detected an asteroid called 33 Polyhymnia which could have an element denser than anything found on Earth.

Clio was Muse of history, Urania of astronomy, Melpomene of tragedy, Thalia of comedy, Terpsichore of the dance, Calliope of epic poetry, Erato of love-poetry, Polyhymnia of songs to the gods, Euterpe of lyric poetry.

Sure enough, Apollo goes onto both knees soon after the three muses — Terpsichore, Calliope and Polyhymnia — have joined him.

He was a teacher of emotional intelligence and writing at American University’s Osher Lifelong Learning Institute and a singer with the Polyhymnia Chamber Chorus, where he was board president.

A bit — it sometimes felt like Calliope and Polyhymnia were antsy for a night out on the town.
