Hi all.
The preamble:
Read clockwise from 1, the perimeter gives relevant subjects and part of a quotation; unchecked letters could form HOLY ANTHEM FLEW. Applying the full quotation, solvers must replace a name featured in six contiguous cells with another, leaving only real words or names. Chambers Dictionary (2016) is recommended.
Often in puzzles like these I will avert my gaze from the perimeter until the very end. Not so this time. I used some of the outer words to help with a few straggling answers as I pieced together the partial quotation:
ANGELS … WHEN THEY ARE TOGETHER EN FAMILLE, THEY PLAY …
The full quote comes from the Swiss theologian Karl Barth. From Oxford Reference:
“It may be that when the angels go about their task of praising God, they play only Bach. I am sure, however, that when they are together en famille, they play Mozart.”
It was then just a matter of “applying the quotation” by finding in the grid JS BACH and replacing him with MOZART. Divine, thanks Raffles!
If there is a setter’s blog for this puzzle it will be available after 9am here.
