Then Ananias answered, Lord, I have heard by many of this man, how much evil he
hath done to thy saints at Jerusalem:
And here he hath authority from the chief priests to bind all that call on thy name.
But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my
name before the Gentiles, and kings, and the children of Israel:
For I will shew him how great things he must suffer for my name’s sake.
And Ananias went his way, and entered into the house; and putting his hands on him
said, Brother Saul, the Lord, even Jesus, that appeared unto thee in the way as thou
camest, hath sent me, that thou mightest receive thy sight, and be filled with the Holy
Ghost.
And immediately there fell from his eyes as it had been scales: and he received sight
forthwith, and arose, and was baptized.
(Acts 9:1–18)
Paul, still known by his old name, Saul, has a vision of Christ on the road
to Damascus, and he is blinded. For three days he lives in darkness, fasting,
until Christ exhorts the disciple Ananias to come to him in the house
of Judas. There Ananias puts his hands on Saul, “and immediately there fell
from his eyes as it had been scales, and he received sight forthwith”. The first
part of the text is therefore an inversion of Mark chapter 8 (text 11), while
the last, being a reversal of the inversion, agrees with it. Saul’s blindness is
temporary, inflicted upon him at the conversion; rather than connoting the
Fall, blindness represents the opposite, some kind of hallowing. Saul used
to be evil, but he has repented and become a new man, a disciple of Christ.
Another vision presages his healing by Ananias, and eventually it is achieved
in the flesh. Saul returns to the normal, everyday world, but transfigured,
and he assumes a new place in it. In contrast, the girl in the troll text simply
resumed her lowly existence after the disenchantment (text 6), and
Adam and Eve were thrust into a similar position (text 8). Saul, on the
other hand, is at least partially exalted from his fallen status.
The structure might be rendered as:
Sight – blinding in the vision – blindness – healing – sight
A metaphorical blinding with quite different connotations and performed
for slightly other reasons is mentioned in Mårten Thors’ 1891 collection. A
boy affronts two “fine damsels” and must suffer his punishment for it:
