The Beloved Disciple

Who was the Beloved Disciple? Mentioned five times in the gospel of John, but never named, scholars have speculated about the identity of the "disciple whom Jesus loved" for centuries. Could it be John himself, or Peter, or even Mary Magdalene? Or is it a code for a disciple whose identity had to remain secret? It's a two thousand year old mystery, and the Naked Archaeologist is on the case.
