The title of this particular poem needs some explaining. It was inspired by a book I read a while ago about the history of symbols and their ever-changing meaning across all cultures. Here are the definitions of the terms used in the title of this poem:
Obolus - the proper name for the division symbol ÷ used in mathematics
ISOTYPES - international signs that use easy to understand images as symbols that can be understood in any language, and regardless of education level (i.e. those who cannot read)

THE OBOLUS AND THE ISOTYPES

These cuckoons
of a few days
Between extremes of day and night
are what I live for.
Somehow I arrived
at this modern life:
it surged towards me
like liquid glass
moving in molten streams
crystal clear and clinging to the feet of angels
briefly like curtains
before merging with the flow
across every landscape
and on to the lake of fire.
