As promised I am answering some of the Qs from yesterday. This is it folks, my first THREAD.
The drawings are not all perfect copies, but they are usually quite accurate. Likewise, Hay etc couldn't read the texts, but mostly copied them accurately and we are able to read them from the drawings. Check this from TT255 tomb of Roy.
He stopped in Aswan a few times and used it as a base to resupply and to visit nearby places like Philae. There are some drawings in Add Ms 29832 labelled as Hadjer Silsileh, but I have not yet checked these so am not sure the details of what he copied.
I think that Hay's drawings contain both of these things. In some instances he says in his journal he's drawing people, or asking people to be in the drawing. Other times, he doesn't say. Below is a Mr. Coffin, about whom Hay speaks a few times, but in little detail.
Question 4: Thanks @eloquentpeasant
He occasionally talks about other people doing excavations. This usually means clearing sand or opening a tomb. Most common are Yanni and Piccinini, the main dealers. But he also mentions 'digging being done for Lord St Asaph and Mr. Williams.' Hoping to gather a list of names!
Yes, @chrisnaunton will feature Hay in his new book although not in massive detail I believe. I am as excited as you are for its publication though!
This would be quite a challenge given the size and varied nature of the portfolio. Whilst possible to select some important material for themed publication perhaps, it would need permission from the direct descendants of Hay as well as the Library.
No, the Thutmose III object was probably not found with the dagger. This illustration is objects from the Sotheby's 1835 Salt collection sale and Hay drew several objects together, which are probably grouped that way at the sale due to material type. Dagger bought by 'Cureton.'
Hope that these answers are of interest! @Steph_Boonstra @CGraves88 @TheEES please do feel free to share to the original askers!
