I was very attracted to "The Sinister Side" and its discussion about the effect of left-right symbolism in Western art. Indeed, skimming the book revealed some interesting discussions of how artists used the left (heart) side to signal the subject's feelings of love or passion, and the right to signal more rational or moral personality elements. Author James Hall dissects a number of mostly 18th and 17th century paintings this way, which promised to be fascinating. But attempting to read the book, I was stopped by two major flaws. First, Hall's prose style is ponderous and dense, though not technical, making it rather slow going and unenjoyable. Worse, though was the quality and small number of paintings actually reproduced. Half the fun in reading about a glistening tear in a subject's eye or a long "love lock" (a 17th century fashion that demonstrated one's passion) was to see it for oneself in an illustration. But many of the paintings discussed are not illustrated at all, and the one that are included are murky, black-and white repros.
"The Sinister Side" is best suited to those who already know the rather obscure paintings under discussion, or who are willing to look up each and every piece on the internet. Too much work for me.
