This cannot be a temple to Artemis, not only is none of the symbolism Artemisian, her temple would be above ground, please do dig out the source though; Broneer's book on the Lion is available to read online at the Haithi Trust, there is a link at PHDiva (whilst I cannot agree with many of her ideas Dorothy King does post very useful links

and she keeps calling Taphoi, Chubb ho ho)
i do not wish to doubt your English, Effi, but when you say '.. because of what they have found at the perivolos' what is the Greek? Is it 'peri' which might mean 'about' or 'around' ? As I am suspecting this is coming from the undateable single letters (unless they spell out 'Deinokrates' built me'!) or the erroneous conclusions from the measurement.
I am not saying Mrs Peristeri is not a good archaeologist, but there seems to be an idea that has taken hold and become an idee fixe vis-a-vis Deinokrates; it easily happens, NGL Hammond was a good scholar but was a frequent sufferer,for example.
They might find there was less media pressure if they were open about the finds they have. The wall of silence fuels speculation and frustration, Mrs Pigeons (as Google translate renders Peristeri) can hardly vilify Palagaia's suggestion that the thing might be Roman on the grounds of evidence she still has not made public; it certainly seems Hellenistic to me but the style seems later than that to which the archaeologists are wedded, but arguments from style are quite imprecise. There is alot more to dig, I just hope they are remembering that the construction of the mound itself is also an important aspect of understanding its history and function. I am just not hearing anything about that topic.
When you think about, it free-choice is the only possible option.
