There were a couple of classical references in here that I did not understand. Normally I manage to guess what to do from the rest of the clue but this time I needed Wikipedia to come to my aid. History and Classics are not my strong point but I’m certainly not complaining as one of the things I enjoy about crosswords is learning all that new stuff along the way. Thanks Dogberry.
The PDF version of this puzzle did not display correctly when I opened it on my PC. The numbers in the grid were replaced with a seemingly random selection of symbols found on the top line of a keyboard: &, ( and * for example. There is also a typo in 6 down dipomatically, I don’t know if this is related.
