Athena is the goddess of "wisdom and warfare." "And don't forget weaving."
Ares says to Athena, "As much as I love the smell of rotting cow carcass in the morning..." In the 1979 Viet Nam War film 'Apocalypse Now' a character says 'I love the smell of napalm in the morning....It smells like victory'.
