They Have Their Exoduses

Having nearly finished rereading Poul Anderson's Genesis, I began to think about the theme of Exodus and couldn't stop:

we know what the Biblical Book of Exodus is about;

Virgil's Aeneid recounts the exodus of the ancestors of the Romans from Troy to Italy;

Geoffrey of Monmouth's History Of The Kings Of Britain begins with the exodus of the ancestors of the Britons from Troy to Britain;

Poul Anderson's Psychotechnic History ends with the exodus of the human race to the Galactic Center;

Hloch's Sky Book Of Stormgate, which we do not read, recounts the exodus of the ancestors of Stormgate Choth from Ythri to Avalon;

Anderson's Technic History recounts the exodus of human beings from the Solar System to the edge of another spiral arm;

Anderson's Tau Zero recounts the exodus of human beings to a new universe;

James Blish's Earthman, Come Home ends with the exodus of Okies from Arm II of the Milky Way to the Greater Magellanic Cloud;

in Blish's sequel, The Triumph Of Time, Amalfi suggests a further journey to the next galaxy, NGC 6822, a million light years away, but instead the spindizzy-powered planet, He, flies to the metagalactic center where it is possible to create new universes.

As Lewis Carroll's Hatter would say: "That's enough about Exoduses!"

Later the same evening: I did forget at least one Andersonian exodus. Which?
