There seem to be 336 results on a search on bruma in the PHI Latin CDROM (thanks to those who did the search). There is probably more data in the Greek side. And then there is the question of brumalia, which I have not even started on.
I have only one hour this evening which is my own, and the same will be true for most evenings. I cannot grapple with that much data in that sort of time. To digest these, collect or make translations, and tabulate them would require several uninterrupted days at least. This means that I shall have to abandon my wish to find out what this means, by the only certain method, which is to go through the data and see what it all says. Selective quotation is never a good idea. Nor do I propose to spend my entire Christmas holiday on it.
It’s a pity, but the demands of earning a living will prevent me dealing with this further.
