 The confirmation of the Roman origins of Bovisio occurred in 1935 when it was discovered in its territory, a Gallo-Roman tomb containing various household items.The name of Masciago also has Latin origin and should be derived from "Martis ager" (Field of Mars) and would indicate that the location, the Roman era, had been a military camp.Formerly the main economic activity was agricultural, with many of the families engaged in the silkworm.
