Caelum non animum mutant qui trans mare currunt

Those who hurry cross the sea change the sky [upon them], not their souls or state of mind

Notes

Hexameter by Horace (Epistulae I, 11 v.27). Seneca shortens it to Animum debes mutare, non caelum (You must change [your] disposition, not [your] sky) in his Letter to Lucilium XXVIII, 1
