"Monstrum" haiku set

"Monsters? There is also talk of other fabulous human portents, which are not real, but invented: they are symbols of a set reality. This is the case of Geryon, king of Spain, of whom it is said he was born with three bodies: in reality, there were three brothers who got on so well that it was almost as if the three bodies shared one soul. This is also the case with the Gorgons, prostitutes with snakes for hair, who with one look turned men into stone. They were said to have only one eye, which they took turns in using. In reality, they were three sisters all equally beautiful, almost as one to the eye, the sight of whom stunned men so much they fancied that the sisters had turned them into stone." - Etymologiae (a monastic encyclopedia entry I quote not so as to accept or affirm literal truth, but rather quote due to its enlightened attitude... and to introduce this haiku set's theme of 'monstrosity'(which in Latin is 'monstrum.')

Yankee eagles fly
over Rome's brackish canals
bearing robot 'huns'

likewise, Yankee pride
ebbs from Asia, as China
sparks from dead red coals

Fortuna's slick die
rests not on human orders
but shifts by night sky

meanwhile, "zombies" walk
and talk of Pythagoras...
in blue, sun-lit air

some even dare to bear
signs before Dracula's five
walled 'winter palace'

while 'myth's' finned mermaids
swim round the giant golden
heart of brave Greenland
