In a post at The Volokh Conspiracy, Stewart Baker includes a picture of the statue that stands outside the Federal Trade Commission (he credits JoeInSouthernCA):

When I worked in D.C. 20+ years ago, I often walked past the statue. My friends and I liked to think of it as the allegorical depiction of Bureaucracy restraining Trade.

Dicaearchus, that great and prolific Peripatetic, wrote a work called On the Extinction of Human Life. Having assembled the other causes – floods, epidemics, ravages of nature, sudden invasions by hordes of wild beasts, the onset of which he demonstrates has caused the exstirpation of certain races – he then shows how many more men by contrast have been wiped out by attacks made by other men in wars or civil commotions, than by all other disasters.

(Cicero, De Officiis 2.16, tr. P. G. Walsh, Oxford, 2000)

The Latin:

Est Dicaearchi liber de interitu hominum, Peripatetici magni et copiosi, qui collectis ceteris causis eluvionis, pestilentiae, vastitatis, beluarum etiam repentinae multitudinis, quarum impetu docet quaedam hominum genera esse consumpta, deinde comparat, quanto plures deleti sint homines hominum impetu, id est bellis aut seditionibus, quam omni reliqua calamitate.
