A villanelle

Explanation:

Villanelle comes from the word villano, in Italian, which means “peasant.’ Actually, villanelle is a name given to a dance song coupled with pastoral themes. In literature, though, it is a poetic device. In a villanelle, the poem must have 19 lines in a fixed form of five tercets and a quartrain.

The fixed form is as follows:

(A1) refrain 1

Line 2 (b)

(A2) refrain 2

Line 4 (a)

Line 5 (b)

(A1) refrain 1

Line 7 (a)

Line 8 (b)

(A2) refrain 2

Line 10 (a)

Line 11 (b)

(A1) refrain 1

Line 13 (a)

Line 14 (b)

(A2) refrain 2

Line 16 (a)

Line 17 (b)

(A1) refrain 1

(A2) refrain 2

"Old age should burn and rave at close of day..." is one of the refrains of the poem, which is a vilanelle.
