The approach to Old English (OE) poetic meter traditionally taken is to describe the meter in terms of a list of foot or verse (half-line) types. It has been suggested that this approach, however, is open to criticism on several points First, a list of metrical types is unconstrained in that there is no principled reason why other members may not be added to the list.

A description in the form of a list therefore cannot rule out unmetrical lines (Halle and Keyser “Iambic Pentameter”). This thesis proposes a model of OE poetic meter based on Hanson and Kiparsky’s parametric theory of universal meter. Hanson and ...
