Update 2/1/16: Been wanting to get this on here for some time. Corvus is also a constellation, and it's worth noting in the context of this thread. I will be adding a new section at the bottom called "Corvus Related Facts" which will house the below content:
The Corvus Constellation
Corvus is a small constellation in the Southern Celestial hemisphere. It includes 11 stars, with one of those stars having two debris disks. The constellation itself is named after the latin word for "crow" or "raven".
An 1825 painting showcasing various constellations, including Corvus directly in the middle (the Crow). A legend associated with the Corvus constellation is that a crow was doing a task for Apollo and getting him water, the crow stopped to eat some figs but then lied about it to Apollo. The crow said that a snake had prevented it from getting the water quickly, while gripping the snake in it's talons - Apollo knew he was lying, and threw the crow, the cup (for water), and the snake into outer space. The cup is meant to be just out of reach to further punish the crow, so he is forever thirsty.
To me this is very interesting, as we can now confirm two types of symbolism from Black Ops 3 present in the Black Ops universe. Iterations on serpents in the past include Shangri-La, and Die Rise:
(Shangir La, Nāga statue)
(Die Rise, dragon)
To me, the cup could easily symbolize the Holy Grail - an artifact of great power that Hitler desperately wanted for his own. All this together is some strong imagery that lends itself to much speculation.
