Giuseppe Mura (1943- ) is an enthusiastic supporter of the idea of a Sardinian Atlantis, following in the footsteps of Giovanni Lilliu. In 2009, he published Sardegna: l’isola felice di Nausicàa  in which he expanded on his ideas.
Specifically, he identifies the Gulf of Cagliari as the location of the Pillars of Heracles(a) and outlines in detail how the Plain of Campidano to the north and the region generally conforms to Plato’s description of the city of Atlantis.
Giovanni Lilliu (1914-2012) was a highly respected Sardinian archaeologist and politician. He was also a recognised expert on the Nuraghic culture of Sardinia. His contribution to the Atlantis debate is to locate the Pillars of Heracles at the Strait of Sicily or more precisely at Cape Bon in Tunisia and Lilybaeum in Sicily.
