al-ʿAbbās ibn Saʿīd al-Jawharī

al-ʿAbbās ibn Saʿid al-Jawharī (in arabo العباس بن سعيد الجوهري‎^?; Baghdad, 800 – Baghdad, 860) è stato un matematico e astronomo persiano.

Geometra che operò nella Bayt al-Ḥikma di Baghdad e, per breve tempo, a Damasco, dove condusse osservazioni astronomiche.

Era probabilmente di origini persiane.^[1]

Il suo lavoro principale fu il Commentario degli Elementi di Euclide (in arabo كتاب العناصر لإقليدس‎^?, Kitāb al-ʿanāṣir li-Uqlīdis) che ospitava anche quasi 50 proposte filosofiche e una proposta logica del V postulato di Euclide.
