On the more definite side, with a dash of art history, William Carlos Williams - 'Landscape with the Fall of Icarus'.
And to go with it the WH Auden version of the same painting, Musee des Beaux Arts:
Musee des Beaux Arts
About suffering they were never wrong,
The old Masters: how well they understood
Its human position: how it takes place
While someone else is eating or opening a window or just walking dully along;
How, when the aged are reverently, passionately waiting
For the miraculous birth, there always must be
Children who did not specially want it to happen, skating
On a pond at the edge of the wood:
They never forgot
That even the dreadful martyrdom must run its course
Anyhow in a corner, some untidy spot
Where the dogs go on with their doggy life and the torturer's horse
Scratches its innocent behind on a tree.
In Breughel's Icarus, for instance: how everything turns away
Quite leisurely from the disaster; the ploughman may
Have heard the splash, the forsaken cry,
But for him it was not an important failure; the sun shone
As it had to on the white legs disappearing into the green
Water, and the expensive delicate ship that must have seen
Something amazing, a boy falling out of the sky,
Had somewhere to get to and sailed calmly on.
-- WH Auden
On the topic of mythology and Gaiman, "The Day the Saucers Came" is quite good for modern myth (as opposed to classical). There's also, for that NZ thing, Glenn Colquhoun's book How We Fell, which is packed with various references. There's one I like particularly with some biblical references. If you're willing to go for the Bible as a mythology, there would be a hell of a lot. (There's the Māori Jesus poem by Baxter, for example.)
Just for the record, I would have loved an English curriculum based around mythology.
