Oculus Two

When the Prince of Wales (later King George IV) wanted to woo his estranged lover back, he sent her a miniature painting of his eye with the note:  I send you a parcel, and I send you at the same time an eye. If you have not totally forgotten the whole countenance, I think the likeness will strike you. After that, bejeweled Lover's Eyes were worn as a symbol of loyalty and devotion to the person whose eye adorned the tiny painting.
