In the original Deities and Demigods, he was listed as:
F: 11
MU: 3
Th: 15
S: 16
I: 18
W; 14
D: 19
C: 17
CH: 18
So, I think that you'd put him a touch higher on the 5e scale. Then again, it's all pretty arbitrary.
EDIT- Which is to say, no matter what edition you use, mapping literary fantasy characters to D&D has always been an inexact science at best. And pulling stuff out of your posterior at worse.
Deities and Demigods may have beefed up their stats to discourage players going and killing heroes and gods, a problem that cropped up after Gods, Demi-Gods & Heroes was published.
