FIVE LEAVES of the Skeireins (I, II, V, VI, VII) are in the Biblioteca Ambrosiana, Milan, where they form Cod. E 147 parte superiore, 4° maj. Leaf VI, which bears the Arabic page numbers 309–310, disappeared from the codex at some time in the course of World War II, probably in 1943. In August of that year Milan underwent three successive nights of heavy bombing, in which thirteen halls of the Ambrosiana were destroyed, ten others damaged, and some 80,000 volumes burned beyond recognition. Fortunately, the Ambrosian Gothic palimpsests were rushed to safety and so escaped the fate of the Giessen document. In 1948 the Ambrosiana provided the writer with fluorescent type ultraviolet photographs of I, II, V, and VII but reported that VI was missing or misplaced. In 1950 a decipherment of I, II, V, and VII was published, followed in 1954 by a reading of the Vatican leaves (III, IV, VIII), but the absence of VI still precluded any attempt to complete the study of the manuscript. Finally, in 1955 it became possible to examine the Skeireins fragments in Vatican City and Milan, and, at the same time, to look for the missing leaf. Leaf VI proved to be misplaced in Cod. Ambros. A. How it came there is a matter for conjecture, but the haste and confusion produced by the 1943 bombing may well account for the misplacement.
