Helena's PowerPoint lecture showed me more about the Parthenon than any other teacher-scholar has.
No we have taken two courses and enjoyed them both.
I will recommend Helena because she is well informed, engaging, and accessible . She welcomes questions. She enjoys presenting Conversations and conveys her enthusiasm to the listeners.
After having done this lecture, I think a very basic lecture works better — an introduction to the acropolis, or intro to the Dutch masters, that sort of thing. Maybe combine with a 360 tour of a collection ? Or team up with a museum that’s willing to allow access to their collection while closed so we can go in person?
Narration by an expert is essential, but you cannot have too many graphics!
