True the idea of "carnival"/mardi gras parts of it were interjected from the slave original culture brought from Africa who tribes celebrated the harvest and seasonal changes in their calendar. However, this tradition of adorning nude slave women on moving auctions....especially if ships came in during the festive period....this painting of and decorating the nude body became a custom...and the real reason for it got lost along the way..but it was to attract the slave buyers. Additionally, in different places, different things occurred like mardi gras for example which is the same celebration. But has a whole different storyline in New Orleans where Native Americans used this event to hide behind masks and settle their disputes among each other while slaves escaped into swamps fleeing the plantations. Massa never knew that those battles among Native Americans were really a ploy/a distraction to help free slaves. So it depends where you are. But!
