The wearing of ankelrts as they used to be called dates back to the pre Roman times when woman are captures a slave bracelet was donned, however this was further broought on bt an anklet meaning that a slave was bought for pleasure. The romans in their own way further improvisecd on this and made it into jewellry rather than just pieces of chain. The more a master appreciated his pleasure slave the more austentachios the jewellry worn ............hope this helps
