Haiku is an ancient form of japanese poetry that reached it's heights in the 17th and 18th century, tho it is still appreciated to this day. There is brevity of wording and the likes of folks like Basho and kenko over the decades were well respected for their work.
Here's one from basho that koi keeoers could appreciate....
loath to let spring go,
birds cry and even fishes'
eyes are wet with tears
