O Again 4. O Clavis O Key, O keys. I lost my Irish grandfather’s keys on a sidewalk in the snow. O necklace of skeleton keys. But I have his broken clock, and photos of his children glued in a celluloid box. O keys, lost keys. I was afraid of Opa who spoke Russian and German and Polish but whose English was remote. I have his silver and porcelain wine tray painted with plums. O lost Clavis, O Radix lost.
