Simeon of Beth Arsham

Simeon of Beth Arsham (Syriac: ܫܡܥܘܢ ܕܒܝܬ ܐܪܫܡ, romanized: Shemʿun di-Beth Arsham) was the Syrian bishop of Beth Arsham in the 6th century, near Seleucia-Ctesiphon. He was known as the "Persian Debater", and played a prominent role in the development of a distinct Miaphysite Church following the 451 Council of Chalcedon. Most biographical information about Simeon is based on the hagiographical Lives of Eastern Saints by John of Ephesus (d. 589).

Simeon's most famous surviving work is his Letter on the Himyarite Martyrs, recounting the massacre of the Christian community of Najran by the South Arabian king Dhu Nuwas. He also wrote a letter on the heresies of the Nestorians. Both have been translated into English. Less widely accepted attributions of authorship include a second letter on the Najran massacre and of a work known as the Book of the Himyarites.
