Luzon (island group) different from Luzones
Traditional milling was accomplished in the 1900s by pounding the palay with a wooden pestle in a stone or wooden mortar called lusong. The first pounding takes off the hull and further pounding removes the bran but also breaks most grains. Further winnowing with a bamboo tray (bilao) separates the hull from the rice grains. This traditional hand-pounding chore, although very laborious and resulted in a lot of broken rice, required two to three skilled men and women to work harmoniously and was actually a form of socializing among young folks in the villages.
In old Latin, Italian, and Portuguese maps, the island is often called "Luçonia" or "Luconia."Luções, [luˈsõjʃ] (also Luzones in Spanish) was a demonym used by Portuguese sailors in Malaysia during the early 1500s, referring to the Kapampangan and Tagalog people who lived in Manila Bay, which was then called Lusong (Kapampangan: Lusung, Portuguese: Luçon), from which Luzon was also derived. The term was also used for Tagalog settlers in Southern Tagalog region. Eventually, the term "Luzones" would refer to the settlers of Luzon island, and later on, would be exclusive to the peoples of Central Luzon.
