Axion cosmic strings have for some time been considered a potential source of enhancement of axion dark matter production, and have been the subject of extensive simulations (for references, see out in recent years). But axion strings are rather peculiar entities. This talk will explore some aspects of these objects, and suggest that they are not likely to play a distinguished role in early universe cosmology.
