This paper reconstructs the seven-century knowledge corridor (3rd–12th centuries CE) through which Greek, Persian, and Indian learning entered the Latin West. Three institutional nodes are examined in sequence: the Sassanid research institution at Gondishapur (est. ~3rd century CE), the Abbasid translation programme centred on Bayt al-Hikma in Baghdad (late 8th–10th centuries CE), and the Toledo translation movement in Castile (late 11th–13th centuries CE). At each node, the paper identifies the human actors, the institutional mechanisms, the texts transferred, and the structural conditions that made transfer possible. The paper argues that the conventional historiography of the European Renaissance — which routinely begins in 14th-century Florence without accounting for its Arabic-Islamic sources — constitutes a systematic erasure of intellectual debt. Four mechanisms of this erasure are documented: name Latinization, the recovery narrative, attribution drift, and the structural incompatibility of the debt with the Crusade narrative. Drawing on primary sources including Agathias of Myrina, Ibn al-Nadim's Fihrist, and the letters of Hunayn ibn Ishaq, and the scholarship of Gutas (1998), Saliba (2007), Burnett (2001), and Lyons (2009), the paper establishes the empirical basis of the transmission thesis and its implications for understanding contemporary civilizational discourse.
