This codex has been dated to the early fifth century C.E., largely because of the changes that occurred in uncial writing between the fifth and sixth centuries, as exemplified in a dated document called the Dioscorides of Vienna.
ऐसा ही बदलाव, वियन्‍ना शहर की डायसकोराइडीज़ नाम के दस्तावेज़ में साफ देखा गया था, जिसकी लिखाई की तारीख का पता लगाया जा चुका था ।
