What purpose did the metal Musk serve?
1) To avoid s|aves eating fruit like apples, pineapples, oranges, cashews, bananas, sugar, etc.. while harvesting them, however they were forced to work consistently on all plantation farms.
2) To stop s|aves from singing their African spiritual songs. Not only spiritual songs also those of war, thus affecting slave masters, as they would motivate them to rebel and f!ght.
3) Lest they teach their children the African local dialects (languages), forcing them to learn foreign languages.
Sometimes s|ave masters would stick an apple in the mouth of enslaved before wearing the metal mask and locking the padlocks so they couldn't talk.
This is just one of the thousands of inhuman treatments our ancestors went through for centuries at the hands of those invaders who gave us Christianity and the religions of mental slavery and brutally forced divisions on Africans.
