Cleopatra's Suicide

I won't go listing all the events following up to Cleopatra's death. Those are known and easy to find on the internet.
On her death is some controversy however. There are two possibilities:
Either she made a deadly venemous snake bite her, or she put an envenomed pin in her arm. Known is she had small marks on her arm, but those could have been made by either.

Also note the difference between venom and poison: venom is safe to drink, if you have no wounds in your mouth or stomach. It's said to taste kind of spicy or salty, but no harm is done if you drink snake venom. So it is ruled out she could have drunk snake venom, as some sources on the internet say.

So she also could have drunk a poison coctail. Possible, but were would the marks on her arm come from? It's unlikely she scratched herself in such a manner, I'd say, but I'm no expert of course.

That remains with two options: a snake, or an envenomed pin. If you read some stuff about Cleopatra, you'll see that she is a devious person, wanting power. She made almost a living legend of herself at the time.
Knowing this, I would say she had a snake bite her. It's highly symbolic, especially if she took a cobra. (For reasons look at blog entry below.)

In several letters/writings of old philosophers(or whatever they're called. A historical source.) there is written about an asp. An asp is a viper species (Vipera aspis) native to Europe, but it doesn't live in Egypt.

The other option is the Egyptian Cobra(Naja haje). Rumored is that Cleopatra had several of her servants attempt suicide with several venomous snake species, and that this one would be the least painful of them all.
I find it believable. Some guy named Cristoph Schäfer said in the Daily Telegraph(He is for the poison coctail possibility): "She would never want to die to a slow death, one that would deform her."
Stupid! He should have made sure first what kind of venom the Egyptian Cobra posseses.
It posseses neurotixic venom, which paralyses and makes the heart and lungs stop functioning. Perhaps it would be a panicky death, because of the sensation not being able to breath- but it surely wouldn't deform her. It seems to me that he has simply repeated something he vaguely heard somewhere else. There is indeed snake venom that deforms the flesh, but that is hemotoxic venom, not neurotoxic.

So I think that she killed herself by smuggling an Egyptian Cobra into the room. It's highly symbolic, speaks to the imagination and relatively painless. However, until her grave and body are found, which is highly unlikely, we will never know the truth. Would we want to though? Sometimes it is good for the human to know he can't know everything. If he would, what reason would there be to live for? I'd like for this to remain a mystery for ever. What do you think?
