In
T.S. Eliot's
The Waste Land, he cites quite
a few
pieces by other poets. In this case (and the
line directly preceding it) he is quoting the
Prothalamion of
Edmund Spenser (1552-1599),
a fine poet,
tho his spelling be shaky.
The poet describes a flock of nymphs (which Eliot
sees depart) preparing for a wedding.
Each stanza of the poem ends with the line:
Sweete Themmes! runne softly, till I end my Song.
