“None but himself can be his parallel” is a line from The Double Falsehood of Louis Theobald (1691-1744), but it comes originally from Seneca (Hercules Furens, Act I, Sc. I):

(Do you seek the equal of Alcides?
No one is except himself.)
I copied the above sonnet from Gossip in a Library by Edmund Gosse (1891), partly because Mr. Gosse said of it, “Anthologies are not edited in a truly catholic spirit, or they would contain this very remarkable sonnet.” I hardly think this, but the lines seem sufficiently interesting to quote.
