[1] In his younger days, Gabriel resided and worked at the Resava (Manasija) Monastery, built between 1407 and 1418 by Despot Stefan Lazarević.
According to Constantine of Kostenets, Resava was built specifically as a centre for the followers of the Hesychasm movement, showing that Stefan held them in great esteem.
Stefan endowed Resava generously with icons and books, and established a scriptorium and a translation school within the monastery.
Old texts were corrected and copied and many were translated from Hebrew, Greek, Old Armenian, Old Georgian, Coptic, Syriac, and Old Latin.
Most of the scribes working in the scriptorium after completing their apprenticeship left for other monasteries in the then Serbian Empire.
