Mary McCallum left a comment on yesterday's Syrenka post that reminded me of a poem I'd written, oh, perhaps a decade ago. This set me off on a late night hunt. I'd hoped to find it and type it up here for today, but apparently the fish that's in it has discovered its fins and swum the poem into hiding. Never mind, it'll turn up. Meantime, staying with the mermaid theme (in itself, a totally unexpected little tributary) here is a poem from John Donne ---
Go and catch a falling starre
Get with child a mandrake's roote
Tell me where all past years are,
Or who cleft the devil's foote.
Teach me to hear the mermaid's singing;
Or to keep off envy's stinging.
And finde
What winde
Serves to advance an honest mind.
John Donne

In the late 1850s, a 1233 ton ship name Mermaid made many voyages between London & Auckland, Liverpool & Lyttleton (I stumbled on this passenger list on the NZ Yesteryears site).
