From D K-T: "Pausanias mentions the bones of Tantalus in 2.22.2-2.22.3 and I was wondering if you feel he is referring to Tantalus, who is punished by Hades without being able to eat or drink, Tantalus, who is killed by Agamemnon and was married to Klytaimnestra, or the more unlikely Tantalus who was a son of Niobe. I did some research and a scholar has already considered this question on the page which this links to ( https://books.google.ca/books?id=CetszVxoxAoC&pg=PA202&lpg=PA202&dq=argos+bones+of+tantalus&source=bl&ots=rXVR3x-O98&sig=MdgPq8447CQNE1FZXpl2c_3ShUo&hl=en&sa=X&ved=0ahUKEwiAxvzHm8zZAhWS3oMKHaxuA6cQ6AEIKTAA#v=onepage&q=argos%20bones%20of%20tantalus&f=false ) but I would still appreciate your input." I can't find a Tantalus who is the son of Niobe; most of them aren't named. There might have been one, but if so he died with all her other children, and there's nothing special about him, so I doubt that he's the one. Tantalus son of Thyestes, first husband of Klytaimnestra, or possibly eaten in a stew by his father along with all the other kids, and likewise died childless (and possibly as a child, in a group of children), so likewise isn't especially important. Tantalus the FATHER of Niobe is the father of Pelops, and the one who is being tormented in the underworld, and the one who founded the entire clan of Pelops, so he's the important one. I would pick him. If it had been another Tantalus Pausanias would have specified.
