In the 1880s, Sievers proposed that in Old English words such as *feorhes, the loss of the post-consonantal *h caused compensatory lengthening of the vowel: fēores. Since there are no unambiguous traces of this sound change in later English, widespread analogical restitution of the short vowels was assumed (e.g. from feorh). The evidence for this lengthening is largely metrical. I argue that while Sievers is correct that words like <feores> often need to scan with a heavy initial syllable, this need not be explained by a general lengthening in the language at large. Indeed, the distribution of where heavy scansions are required in verse is typical for metrical archaisms: late prehistoric metrical values of words preserved for poetic convenience. Just as wundor ‘marvel’ can continue to be scanned as monosyllabic *wundr, or contracted hēan can scan as disyllabic *hēahan, so can light-syllabled feores continue to scan as heavy *feorhes. The same sets of poems that prefer non-epenthesized or non-contracted forms also prefer the heavy scansions of feores-type words. If heavy scansions of feores-words are seen as a matter of poetic convention, then the hypothesis of compensatory lengthening in the language generally is left without evidence and should be rejected.
