There's a useful lesson here. On first read I did not get these and my review was going to be built around what it means to get poetry and to what extent it's like getting jokes, getting art, getting measles, getting drunk.
Second and third reads improved things immeasurably. These are uniformly strong. My heart sinks when poems arrive in cantos but given the heart, brain and skill displayed here I can forgive in thus instance.
Still do not get them but less worried now.
