The facts on the card
The card carries these facts from its Wikipedia article.
- He is known to have written an optical treatise around 984.
- The text of this treatise was reconstructed by Roshdi Rashed from two manuscripts.: Damascus, al-Ẓāhirīya MS 4871, 3 fols., and Tehran, Millī MS 867, 51 fols.
- The Tehran manuscript is much longer, but it is badly damaged, and the Damascus manuscript contains a section missing entirely from the Tehran manuscript.
Why it is Common
Rarity in WikiCards follows a year of Wikipedia page views: the most read articles become Epic and Legendary cards. The Ibn Sahl article was read about 13,000 times in a year. ATK comes from the length of the article and DEF from its quality, so this card hits with 58 and blocks with 28: each hit it takes is cut by 11 %.
