Aside from a grammatical error, a minor quibble to be sure, nicely done. Well-sourced, but regrettably, the full research paper referenced is not available for perusal. Nevertheless, what is to be had makes for worthwhile additional study. The Author's take here is a good one. Quoting and commentary are helpfully expository. The inclusion of some of the referenced art in photographs is splendid and most welcome. The Writer does a fine job of examining an interesting and fascinating subject from an exceedingly informative perspective. A decidedly worthwhile read. Four stars!
