School of NisibisThe School of Nisibis (ܐܣܟܘܠܐ ܕܢܨܝܒܝܢ, for a time absorbed into the School of Edessa) was an educational establishment in Nisibis (now Nusaybin, Turkey). It was an important spiritual centre of the early Church of the East, and like the Academy of Gondishapur, it is sometimes referred to as the world's first university. The school had three primary departments teaching: theology, philosophy and medicine. Its most famous teacher was Narsai, formerly head of the School of Edessa. The school was founded in 350 in Nisibis.

He is the most important writer of the East Syriac Christianity after Mar Aprem.
