Part I contains five chapters which are devoted to different linguistic phenomena, and problems in quantifying them are set out in each. Part II argues that chronology is just one part of a much wider picture, and that not only dialect but also style is a highly salient factor in understanding language variation throughout the poems. This notion of style is linked to the linguistic concept of register, and it is argued that the prehistory of different kinds of poetry led to the creation of different registers for different (sub)genres within the corpus. McConnell therefore takes a linguistic approach to understanding the literary history of early Greek hexameter poetry.
