Koen Gh,
This reply here is in itself problematic: the coins you show are unlikely to have been seen by anyone in the 15th C, as I explained to you in another thread.
If you have evidence that this particular coin was in the hands of someone in the 15th C, or that the same design is represented in an MS likely to have been seen by someone from that period, then that would be better. Also, no one in the 15th C would have seen the Pharos everyday, because it had been severely damaged by a series of earthquakes, and was in ruins.
MarcoP is correct in reminding you that you have already been told (by ReneZ but also by me) about the problem of proving transmission in the iconography you rely on.
ETA, the artefact you use as a comparison with the snake is from a death mask. In the 15th C, it (and all other similar masks) was still in the tomb.
