A detailed theoretical investigation of the reflection of an atomic de Broglie wave at an evanescent wave mirror is presented. The classical and the semiclassical descriptions of the reflection process are reviewed, and a full wave-mechanical approach based on the analytical soution of the corresponding Schrödinger equation is presented. The phase shift at reflection is calculated exactly and interpreted in terms of instantaneous reflection of the atom at an effective mirror. Besides the semiclassical regime of reflection describable by the WKB method, a pure quantum regime of reflection is identified in the limit where the incident de Broglie wavelength is large compared to the evanescent wave decay length.

A close comparison of the use of language, style and method of composition of the sizable corpus of Old English and Old Irish vernacular sermons (10c and 11c) show that both cultures make use of a preaching rhetoric which is deeply indebted to oral styles of preaching and geared towards the aural reception of the spoken word. Both tend to resort to a flamboyant pastoralism and excel in elaborate verbal artistry. While received scholarship claims that the English were subject to Irish influence in this respect because of the existence Hiberno-Latin analogues, this short monograph argues that this is very unlikely. Rather both traditions are independently indebted to 7c to 9c Continental preaching styles, the evidence of which shows that there was both a plain preaching mode (the "fisherman's" mode) and an elaborate (or "Asian") one. The use of both was advocated,depending on the occasion, by St. Augustin's "De doctrina christiana." In the Insular context of vernacular preaching, the latter seems to have been functioned as a favoured art form.
