Nostos in Greek means the return -- that which is eternally impossible, which speaks to the heart and to the imagination ; the return within the confounded space and time where hope remains.
Nostos is the fundamental root of the poignant feeling called nostalgia, the pain of nostos.

Here, perfume is the vehicle of the return to which one aspires in vain. Like an intense and deep incense that would have burned for three thousand years, the perfume celebrates the Homeric epic of that most beautiful of heroes, whose anger and its unpredictable consequences made the Trojan War.
The totemic figure of the desired but unfulfilled nostos is Achilles. This is not the nostos of Ulysses and his Odyssey; here, it is Achilles, the emblem of the perfume, conceived by the gods, born of love, like the Trojan war.
