The journey through another world, beyond bad dreams beyond the memories of a murdered generation, cartographed in captivity by bare survivors makes sacristans of us all. The old ones go our bail, we oblate preachers of our tribes. Be careful, they say, don't hock the beads of kinship agonies; the moire-effect of unfamiliar hymns upon our own, a change in pitch or shrillness of the voice transforms the ways of song to words of poetry or prose and makes distinctions no one recognizes. Surrounded and absorbed, we tread like Etruscans on the edge of useless law; we pray to the giver of prayer, we give the cane whistle in ceremony, we swing the heavy silver chain of incense burners. Migration makes new citizens of Rome.
