that "Both manuscripts were apparently written before the development of a more formal Biblical majuscule style, which began to develop in the late second and early third centuries." In this respect, Porter also notes that although the hooked apostrophe form found in the Cologne fragment of P.Egerton 2 is unusual in the second century, there is at least one known dated example in a papyrus of 101 CE and three others of mid or late second century date. "The result is to bring the two manuscripts together, somewhere in the middle of the second century, perhaps tending towards the early part of it." Stanley Porter has also questioned Nongbri's assertion that valid comparisons can be made between 𝔓 and documentary papyri of the later second and early third centuries; noting the warning from Eric Turner that, "Comparison of book hands with dated documentary hands will be less reliable, the intention of the scribe is different in the two cases." and in respect of this Porter cautions against what he terms Nongbri's 'overly skeptical' insistence on disregarding comparators without an explicit date, forcing comparators for literary texts inappropriately to be confined to purely documentary hands. Porter suggests that Nongbri's proposed late second and third century comparators are in several cases quite different from 𝔓 so that they force comparison to focus on detailed letter forms without consideration of the overall formation, trajectory and style of the script. If, rather than undertaking comparisons document by document, typological letter comparisons are instead applied using published series of dated representative script alphabets, then, Porter asserts, both 𝔓 and P.Egerton 2 "fit comfortably within the second century. There are of course some letters that are similar to those in the third century (as there are some in the first century) but the letters that tend to be given the most individualization, such as alpha, mu and even sigma, appear to be second century." Both Porter and Nongbri note that Eric Turner, notwithstanding his proposal of P.Amh. 2.78 as a parallel for 𝔓, nevertheless continued to maintain that "The Rylands papyrus may therefore be accepted as of the first half of the second century". Nongbri has subsequently pointed out the limited usefulness of Porter's study due to the fact that it makes no reference to manuscripts with secure dates and thus is entirely circular (several undated manuscripts are used to provide a date for another undated
