I hadn't taken volume 2c, the critical notes, out of the plastic wrap when I took the photo. Now I have to spend some time clearing space for the score in my bookcases.
The advantage of having the physical score, rather than trying to read a PDF of a deeply flawed 19th c. edition, is that, well, there it is. And on the very first page there's a line of music I had not really noticed in the PDF: the top line isn't the piccolo, it's for "doubles flute antiques," which are supposed to be on stage on the grave of Achilles. Apparently what Berlioz expected was that the oboes would play this, as can be heard on every recording of the work.
