Gusana is the name of an artificial lake and of the surrounding area, in the territory of Gavoi, Sardinia, Italy.
Most of the cheese is now produced on the island, especially in Gavoi.
In the 1st century AD, some relevant groups of Hebrews were deported to Sardinia, bringing various influences; the Christianization of the island would probably have brought Hebrews to convert to a sort of independent cult of Sant'Antioco (perhaps a way to preserve some aspects of their ethnicity under a Christian form), still present in Gavoi.
