A cosmo is a belief about the world.  "Never sleep under a walnut tree."  This is a saying in Corsica and a Corsican cosmo.  According to letstalkaboutCorsica.com, each Corsican village has its own church, and in front of each of these churches is some type of tree.  The acceptable types of trees for the front of these churches are chestnut trees, olive trees, oak trees and even lime trees, however walnut trees are forbidden because Corsicans view these walnut trees as a "negative sign."
