Poets who Count

For some poets, counting is part of the language of the poem. For others, counting determines the structure. Here are two poems of the former sort -- "Counting" by British poet Philip Larkin (1922-1985) and "Adding It Up" by New England poet Philip Booth (1925-2007) -- followed by opening stanzas of a poem for which counting is part of both content and structure:  "Millennium" by mathematician Peter Cameron .
