   • 1663, Samuel Butler, Hudibras, part 1, canto 1:

     [...] But with more lucky hit than those

     That use to make the stars depose,

     Like knights o' th' post, and falsely charge

     Upon themselves what others forge;

     As if they were consenting to

     All mischief in the world men do [...]

   • Nash

     A knight of the post […] quoth he, for so I am termed; a fellow that will swear you anything for twelve pence.
