The story is cleopatra used asps to commit suicide, not murder. She had them smuggled in a jar or dates or something.
The poison is (apparently) quite painless, a neurotoxin, and you just go to sleep and don’t wake up. So it has been a pretty common method of suicide back home for 4000 years.
The main issue with the story is an “asp” is more properly known as the Egyptian cobra, and it’s a big black snake that quickly grows to 1.5 meters. So it’s unlikely to be able to be smuggled in a jar of any kind.
That said you could probably get several juveniles and get the job done.
I saw a “history” show that said Cleopatra experimented on prisoners to see which method would produce the most dignified death.
Ah, that’s right, suicide.
I live in Maine, which claims to be the only state without poisonous snakes in the U.S.A.
Those snakes in Israel sound nasty.
I’m glad we don’t have asps here, although we do have asses in our Congressional delegation, and a number of snakes in our state government.
