I’ve always thought it was cool that the two moons of the planet Mars (itself named after a war god) were named Phobos (fear) and Deimos (terror), but am surprised to encounter it right here in the Theogony 934 — Phobos and Deimos are in fact Ares’ (ie Mars’) sons:
αὐτὰρ Ἄρηι /ῥινοτόρῳ Κυθέρεια Φόβον καὶ Δεῖμον ἔτικτε δεινούς
“But to shield piercing Ares Aphrodite bore Phobos and Deimos, terrible ones…”
