The traditional cornucopia was a curved goat's horn filled to brim with fruits and grains. According to Greek legend, Amalthea (a goat) broke one of her horns and offered it to Greek God Zeus as a sign of reverence. As a sign of gratitude, Zeus later set the goat's image in the sky also known as constellation Capricorn. Cornucopia is the most common symbol of a harvest festival. It is also known as the 'horn of plenty'

Thomas Jefferson thought the concept of Thanksgiving was "the most ridiculous idea I've ever heard."
