Al-Hawari

Early-14th-century Maghrebi mathematician (fl. early 1300s, from Miṣrāta), one of Ibn al-Banna's own students, who in 1305 wrote al-Lubāb, the earliest surviving commentary on Ibn al-Banna's Talkhīṣ aʿmāl al-ḥisāb — composed during the master's own lifetime, making it the closest primary-adjacent source to Ibn al-Banna's arithmetic that survives. Matters to this vault as the subject of the single Tier 1 source found that purpose-built an inventory of the Talkhīṣ tradition's actual contents (Abdeljaouad & Oaks 2013) — a 44-page catalogue of what al-Hawārī's commentary adds, operation by operation, that never mentions lattice, gelosia, or shabakh multiplication, the strongest evidence yet against Wikipedia's attribution of the method to Ibn al-Banna's own text.
