PERF 558 is the oldest surviving Arabic papyrus, found in Heracleopolis in Egypt, and is also the oldest dated Arabic text using the Islamic era, dating to 643. It is a bilingual Arabic-Greek fragment, consisting of a tax receipt, or as it puts it "Document concerning the delivery of sheep to the Magarites and other people who arrived, as a down-payment of the taxes of the first indiction." After excavation, the papyrus was collected by Archduke Rainer Ferdinand of Austria, who donated it to the Austrian National Library in 1899. The museum authority put it in the Erzherzog Rainer Papyrus Collection. This text was published in 1932 by Adolf Grohmann and in 2009 by Demiri and Römer.
