Under the Spell of Rhymes

I came across the third word, spell,
in the local library's lost and found,
next to a smartphone heavy as a dumbbell.
The second word, the article of the,
was bestowed upon me by a grand poobah,
the young, recently crowned Maharajah.
My readers shall not wonder much longer
where I found the very first word, under:
I discovered under right above
the fourth word, the preposition of.
The last word, though I seeked many times,
it was only at the end that I found rhymes.
