We trace out all the veins of the earth, and yet, living upon it, undermined as it is beneath our feet, are astonished that it should occasionally cleave asunder or tremble: as though, forsooth, these signs could be any other than expressions of the indignation felt by our sacred parent!

Man has learned how to challenge both Nature and art to become the incitements to vice! His very cups he has delighted to engrave with libidinous subjects, and he takes pleasure in drinking from vessels of obscene form!

How innocent, how happy, how truly delightful, even, would life be if we were to desire nothing but what is to be found upon the face of the earth: in a word, nothing but what is provided ready to our hands!

Pliny the Elder Quotes
