onos

Onos - oh'noss - n. - A Greek concept of rational worry; represented by Homer's Odyssey in Athena, a Greek Goddess, and many Greek heroes in other traditional works, it is considered a positive attribute.
Romans considered "onos" a negative attribute, like Odysseus' intelligence, and it became transmuted into the less-positive "onus," or "burden."

Athena's onos was manifested in her fear of Poseidon's threat to Odysseus' homecoming.
