Well, this is a selection of 40 of the 72 or so tales, but if they are representative of the whole I found the majority of them a little stark, dreary and sordid. Marguerite had read the Decameron (which I have not yet) and was inspired to pen her Heptameron. I hope this doesn't reflect on Boccaccio's work, which I am expecting to be more in line with the Canterbury Tales.
Chastity sure was a precious thing back in the day. All the admirable women suffer privation, ostracism or death rather than part with it. If the translation does her writing any justice I rather admire Marguerite's style, which is ornate by today's standards but still surprisingly clear. However, my impression is that the plots that appealed most to the average 16th C reader revolved around female chastity and male concupiscence, actually a minor twist on today's sexual obsession which lacks the ancient drama from current overuse.
Tale 20 is especially dark, exhibiting a prurient fascination with incest: a mother gets caught in her own ill-conceived (to use a term) scheme to foil her son's desire for a serving girl, gets pregnant by him and produces a daughter. Eventually, the son meets his sister-daughter, her background all unbeknownst to him, falls in love and marries her. The mother suffers her original sin all in silence.
All in all, I enjoyed getting an insight into what passed for literary entertainment several centuries ago ...
