The seventeenth-century Brussels manuscript 8232-33 is an extant Greek witness for the Metastasis of the apostle John. The seminal text edition of the apocryphal Acts of John by Eric Junod and Jean-Daniel Kaestli provides neither a siglum for, nor a comprehensive codicological description of, nor catalogue references concerning this manuscript. The present annotation makes this information available and analyzes the manuscript of the Metastasis with regard to its model, copyist, and time of origin.
