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.
>In 2018, Mura published, also in Italian, Tartesso in Sardegna , the full title of which translates as Tartessos in Sardinia: Reasons, circumstances and methods used by ancient historians and geographers to remove Tartessos (the Tarshish of the Bible) from Caralis and place it in Spanish Andalusia. Caralis is an old name for Cagliari, the Sardinian capital.<
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.
