From my computer display, the transcription of GA1421, frame 1180, line 9, should be more likely "... aiwnos toutou..." and not "... aiwnos autou ...". It appears to me that a ligature for sigma-tau has been taken as an alpha, owing to the poor quality focus on the region in the image. In the same line we have two more sigma-tau ligatures where the focus is better.

Thank you for pointing this out. I agree with you, especially as the accentuation also speaks in favor of this reading. The transcript has now been corrected.
