RS and older source 

You've found one or two errors. While one journal is indeed a reliable source (e.g., peer-reviewed), I probably should have moved that citation when other content was deleted and I re-added it elsewhere. The other direct source being an unsigned article with no peer review known, I'll drop it, subject to confirmation of its citation to Gibbon, ch. 44, for which I plan to look. Both journals were in JStor, but that's not dispositive. Rephrasing a however and nearby text would not have been a problem; I did not intend to communicate supersession, only that the sources disagreed.
