John Bugay posted an item that led me to an interesting graphic purportedly of the new fragment of the Gospel of Mark, together with a transcript of Codex Sinaiticus. Below, I've placed the letters found in the fragment in bold - the other letters are supplied from the transcript of Codex Sinaiticus. Obviously, there are significant lacunae, but I've identified a single variant vis-a-vis Sinaiticus and highlighted it below. The variant is untranslatable, because it is simply a clerical error (omission) in Sinaiticus, which we might speculate was due to the similarity in appearance between the epsilon and theta in the exemplar from which it was copied. Since the fragment does not have error, it is better than Codex Sinaiticus.
(The starting place for the columns, especially for the first few lines, is speculative. Mark 5:15-18 is shown. I'm unaware of whether there is text on the opposite side of the manuscript fragment.)
