Ovid's Metamorphoses ... third edition, ripped-off from Tonson and printed in Ireland in 1727 ... here are the frontispiece pages with their pictorial dedications to a series of high-ranking ladies ... of Volume One, Books One to Seven ... and of Volume Two, Books Eight to Fifteen ... it seems only properly respectful to include such portraits of the ladies as will bring them to life ... BUT THEN, LATER ... mercy me ! ... I had failed to realize i was looking at the cheap rip-off pirate edition ... the original publisher was Jacob Tonson in London ... his printers and engravers and artists did much finer work, as you will see ...

 

VOLUME ONE

https://archive.org/details/ovidsmetamorphos01ovid/mode/2up?view=theater

this is the crude rip-off version printed in Dublin ...

and this is the original ... printed in London ...

... and here is the painted lady ...

in 1727, the duchess of kingston was Isabella Bentinck 

portraits are hard to find but this is a tentative ID ...

... and this is a more positive ID ...
