Nyx (English /ˈnɪks/; Ancient Greek: Νύξ, "Night"; Latin: Nox) is the Greek goddess (or personification) of the night.
A shadowy figure, Nyx stood at or near the beginning of creation and mothered other personified deities such as Hypnos (Sleep) and Thanatos (Death), with Erebus (Darkness).
Her appearances are sparse in surviving mythology, but reveal her as a figure of such exceptional power that she is feared by Zeus himself.
