A question about Haiku please. What do you think really defines a haiku? The 5-7-5, a seasonal nature reference and / or the first two lines turning in the third to apply to an entirely different thought – such as Harold Henderson’s translation of a Basho haiku:
Summer grass: of stalwart warriors splendid dreams the aftermath.
I’m of the mind that it is almost more in the cadence than in any set mechanical formula. But I’m also very fond of that sudden running into a wall of thought you hadn’t seen coming (mixed metaphors?)
