Adam Smith in the beginning of Wealth of Nations has looooooong sentences with tons of commas. I added the breaks, this is actually one paragraph:

Among the savage nations of hunters and fishers, every individual who is able to work is more or less employed in useful labour, and endeavours to provide, as well as he can, the necessaries and conveniencies of life, for himself, and such of his family or tribe as are either too old, or too young, or too infirm, to go a-hunting and fishing.

Such nations, however, are so miserably poor, that, from mere want, they are frequently reduced, or at least think themselves reduced, to the necessity sometimes of directly destroying, and sometimes of abandoning their infants, their old people, and those afflicted with lingering diseases, to perish with hunger, or to be devoured by wild beasts.

Among civilized and thriving nations, on the contrary, though a great number of people do not labour at all, many of whom consume the produce of ten times, frequently of a hundred times, more labour than the greater part of those who work; yet the produce of the whole labour of the society is so great, that all are often abundantly supplied; and a workman, even of the lowest and poorest order, if he is frugal and industrious, may enjoy a greater share of the necessaries and conveniencies of life than it is possible for any savage to acquire.

Run on sentences area awesome. For twelve years my teachers told me not to use them but I defied them all and continue to string together sentences with the wrong uhh... mark thingies to this day!

Reading fucking Dostoevsky and there are almost as many subordinate clauses per sentence as there are nicknames for the characters.

There was some book I had to read over the summer in preparation for AP English my senior year of high school, and it was all just page length stacks of nested clauses where it would just stop in the middle of a sentence, elaborate on some aspect of it, interrupt to elaborate - at least once, usually more - some more, then continue to keep doing this out to an absurd depth, only to meander back to it most of a page later and then either finish it or start another pile of nested clauses. Like look at how I structured that sentence and imagine something ten times worse, and then imagine it happening at least once in every single paragraph and at least once per page.

Also the story was awful in its own right, terrible prose aside. All I can remember of the plot was that the POV character was a dumbass and killed someone by being a dumbass and it all hinged entirely on inscrutable 19th century superstitious sensibilities.

At the end of the year I gave the book to a junior in one of my classes who was going to take AP English the next year and who had to read that same story over the summer.
