Another bit of fun. Poets don't write vaunts much anymore. Try it; it will do you no end of good. To get the ball rolling:
Vaunt
Greater than me you cannot be;
I am a star in motion.
I flow forth like a mighty flood
out to an endless ocean.
A greater than I you cannot find,
a hero born of glory,
filling the space from sun to sun,
like Zeus in ancient story!
Note that I settled for Zeus. I am modest; I don't need more than that.... ;)
