Enigma (Sovereign)

I was known in old Time; and yet, strange to relate,
'Tis a very few years from my very first state.
When I travel--'tis seldom--my Way you may trace;
Yet I'm constantly secretly changing my Place;
I'm weak, and I'm wise; I have Praise and have Blame;
Yet at all times my Value and Worth is the same.
I Nobles create; and yet any of these
May consume and abuse me as much as they please.
Though I Millions command, yet the Poorest may gain
And possess me awhile, though they seldom retain.
Tho' I've Equals ten thousand, all over the Land,
Yet One Crown I possess and have four at Command.
One part of my Character All Men may read,
And that only from such Contradictions is freed:
Who counterfeits me, stakes his Life on the Deed.
