Codex Bodleianus Auct. T. 4. 21 (Misc. 259) is a 12th-century manuscript written in large part on palimpsested parchment. It contains, inter alia, hitherto unknown treatises of (Ps.-)Amphilochius Iconiensis as underlying scripture (scriptio inferior). In 2011 the author discovered these treatises during a research stay at the Bodleian Library in Oxford. The (Ps.-)Amphilochius sections are written in a clear uncial script from the 8th-9th century. A complete edition of the manuscript’s scriptiones inferiores together with a codicological analysis and a palaeographical description is in preparation.
