Papyrus Oxyrhynchus 18 (P. Oxy. 18) is a fragment of the first book of the Histories of Herodotus (chapters 105-106), written in Greek. It was discovered by Grenfell and Hunt in 1897 in Oxyrhynchus. The fragment is dated to the third century AD.[1] It is housed in the British Library (Department of Manuscripts). The text was published by Grenfell and Hunt in 1898.[2]
The manuscript was written on papyrus in the form of a roll. The measurements of the fragment are 182 by 87 mm. The fragment contains 13 lines of text. The text is written in a good-sized round formal uncial hand. The style of writing resembles great biblical codices. It has deep margins. The fragment supports the manuscript tradition though there are a few variations in the form of words representing differences in dialect.[3]
