This collection assembles 25 articles published by Raymond Arveiller as ongoing addenda to "FEW XIX (Orientalia)" in the Zeitschrift für romanische Philologie (ZrP) between 1969 and 1996. It thus supplements "FEW XIX (Orientalia)", which was completed in 1967 and was therefore unable to take into account various sources explored by Arveiller in the last 30 years. As Arveiller died in 1996, the supplements have been assembled unchanged in a special Supplement Volume, with only obvious printing errors emended. It was of course indispensable to compile a new bibliography to accommodate the numerous sources newly drawn on by the author and quoted at the beginning of the articles in the ZrP. The bibliography also encompasses those articles by Arveiller on oriental elements that are not listed in the ZrP addenda. The present volume is an indispensable supplement to "FEW Vol. XIX" and places the study of the oriental elements in Gallo-Romance studies on a new footing in keeping with the state of present-day research.
