This new Oriental Institute series - Late Antique and Medieval Islamic Near East (LAMINE) - aims to publish a variety of scholarly works, including monographs, edited volumes, critical text editions, translations, studies of corpora of documentsin short, any work that offers a significant contribution to understanding the Near East between roughly 200 and 1000 CE. LAMINE 2 investigates Arabic's transformative historical phase, the passage from the pre-Islamic to the Islamic period, through a new approach. It asks, What would Arabic's early history look like if we wrote it based on the documentary evidence? The book frames this question through the linguistic investigation of the Damascus Psalm Fragment (PF), the longest Arabic text composed in Greek letters from the early Islamic period. It is argued that its language is a witness to the Arabic vernacular of the early Islamic period, and then moves to understand its relationship with Arabic of the pre-Islamic period, the Qur'anic Consonantal Text, and the first Islamic century papyri, arguing that all of this material belongs to a dialectal complexed we call Old Higazi. The book concludes by presenting a scenario for the emergence of standard Classical Arabic as the literary language of the late eighth century and beyond.
