San Marco in Lamis (Sammarchese: Sandə Marchə [ˈsændə ˈmærkə]) is a town and comune in the province of Foggia in the Apulia region of southeast Italy.

[3] Popular tradition connects this ritual to the lighting of roads in order to help the mother of Jesus in the search of her son's body.

[4] The Archangel is also thought to protect the mountain against earthquakes: "Santə Məchelə fa lu uardianə intə li gruttə də Montə e accuscì intə pə intə tè abbada tuttə li gruttə e non li fà anchi də demonjə e non fa succedə li tremutə[5]", "Saint Michael guards the grottoes of Monte Sant'Angelo, he controls all the grottoes and guards their interior, he prevents them from becoming full of demons and prevents earthquakes from happening".

The inhabitants of the town speak an Italoromance language, belonging to Southern Italian dialects, which they refer to as Sandəmarchesə.

The difference between the two lies in the definiteness features of the nouns:[7] Other languages of Southern Italy, such as Calabrian varieties, make use of the non-prepositional construction.
