Mythology Summary
Nebro is the name the Gospel of Judas (Codex Tchacos, 2nd century) gives the demiurge: when the twelve angels are made to rule over chaos and the underworld, an angel appears in the cloud with a face blazing like fire and a figure stained with blood, 'whose name was Nebro, which is translated apostate; others called him Yaldabaoth'. Nebro creates six angels and Saklas six more, and from them come the twelve angels who receive each a portion of the heavens and the rulers set over the chaos below. The name is usually derived from Nebruel or from Nimrod (Genesis 10:8-12), the 'mighty hunter before the Lord' whom the gnostics turned into an insult for the creator - a scholarly proposal, not something the text states.
Modern Practice
Read rather than invoked: Nebro belongs to the literary theology of the Gospel of Judas, and modern use is textual and diagnostic - a name for the apostate maker of the rulers, the power that turns away from what is above it and builds a world in its own image.
