 See, for example, Kosei Morimoto, "Taxation in Egypt under the Arab Conquest," Orient (Tokyo) 15 (1979), pp. 71-99, and The Fiscal Administration of Egypt in the Early Islamic Period (Kyoto, 1981), though the emphasis is on other documents. One might have expected something useful in Frazer's revision of Butler's Arab Conquest of Egypt (A.J. Butler, The Arab Conquest of Egypt, 2nd edition revised by P.M. Frazer, Oxford, 1978); but though Frazer's introductory notes have a reasonably good section on the papyrological evidence (pp. lxxvi-lxxxiii), PERF 558 is not dealt with.
 Published in 1911. Caetani was aware of PERF 555, 556, 559 and 561.
