Amanda McKittrick Ros
Amanda McKittrick Ros (1860-1939), author of the novels Irene Iddesleigh, Delina Delaney, and Helen Huddleson, the short story Donald Dudley, the books of verse Poems of Puncture and Fumes of Formation, among other works, has the distinction among many critics of being the worst author in the English language (and possibly the most alliterative as well). Amanda didn't like critics any better than they liked her, calling them "evil-minded snapshots of spleen."
Delina Delaney begins with this impenetrable phrase: "Have you ever visited that portion of Erin's plot that offers its sympathetic soil for the minute survey and scrutinous examination of those in political power, whose decision has wisely been the means before now of converting the stern and prejudiced, and reaching the hand of slight aid to share its strength in augmenting its agricultural richness?" And continues in like vein for 301 pages.
Here's a sample of her verse:
On Visiting Westminster Abbey
A "Reduced Dignity" invited me to muse on its merits
Holy Moses! Have a look!
Flesh decayed in every nook!
Some rare bits of brain lie here,
Mortal loads of beef and beer,
Some of whom are turned to dust,
Every one bids lost to lust;
Royal flesh so tinged with 'blue'
Undergoes the same as you.
Famous some were--yet they died;
Kings--Queens, all of them do rot,
What about them? Now--they're not!
