By John Donne.

Like Esops fellow slaves, O Mercury
Which could do all things, thy faith is; and I
Like Esops Selfe, which nothing, I confesse
I should have had more faith, if thou hadst lesse;
Thy credit lost thy credit: 'Tis sinne to doe,
In this case, as thou wouldst be done unto
To believe all: change thy name: thou art like
Mercury in stealing, but lyest like a Greeke.
