Seems like it, or another version, ought to hang at the Jordan River, where it occurred. Is there some sort of shrine, church or memorial there, commemorating John’s ministry and/or Jesus’ baptism?
Check this out! From the description: “The Baptism Site on the Jordan side of the Jordan River is one of the most important recent discoveries in biblical archaeology. Excavations only began here in 1996, following Jordan’s peace treaty with Israel in 1994, but have already uncovered more than 20 churches, caves and baptismal pools dating from the Roman and Byzantine periods.”
