In a relatively short while, I'll have to write a blog post on this poem, so I've been doing some research into the sources. The first is P.Oxy. 1232, an image of which is the following.
A later source is P.Oxy. 2076, with image below.
From these, I can find most of what the text at Greek Wikisource (very end of page) has. However, there is a bit that is not in these images.

If this is a scrap of papyrus in no way connected to the image above, on what basis do they include it in the poem of the two images above?
