O heart weighed down by so many wings!That's it. Just one line, but it says much more than that to me.
An artichoke is but an artichoke. But put down like this, it reminds me of Wordsworth's sonnet which talks about poor souls "who have felt the weight of too much liberty", which argues that too much freedom doesn't do us good and certainly doesn't make us happier. Having rules up to some points gives a sense of security. Having none gives a sense of uncertainty. Well, too many "wings" can wear us down.
Also for me, it sounds like someone being too tired because he has so many things to do, and he has so many things to do because he can do it. Because he has the "wings" to do it. In fact, your talent, your skills, your knowledge, and your abilities can be a deadly trap that enslaves you.
The moment I read this poem, I don't even think about artichokes anymore.
