deTraci Regula just published a report on a trial program on Crete in which travelers will spend three days with a Knossos curator learning about the ongoing activities there. It includes access to many areas not seen by the ordinary visitor including Villa Ariadne where Sir Arthur Evans lived while excavating Knossos. See the detailed schedule and low cost in her post.
Of course this gives me the idea of doing something similar on Paros. Along with the ongoing work at Despotiko which produces new discoveries every year there are several other active excavations on Paros that would produce more finds if they had more funding. So, if you might be interested in spending one or more days up close and personal with an archeological dig on Paros, let me know. If there is enough interest I will contact the various authorities to make it happen.
Painting of Blue Ladies at Knossos is by Victoria Papale who is conducting a workshop on Paros this year.
