0740: #73 solved, and Lorick #74 I speak of a tree on an island

Lorick #73:

I speak of a tree on an island;

Annotated in red by a neat hand.

My three crimson marks

ignite feverish sparks

in brains where desire's green flames fan!

But first, we solve #74 - here it is one last time:

More than once was this woman abducted

Over seas, from her duty conducted

To a prince, though a wife

came this apple of strife

They were followed... his city, destructed
