Prophets of Scripture
The 16 writing prophets — derived from the books they authored — alongside curated speaking prophets who left no book of their own. Each is placed at their earliest appearance in Scripture; marker size reflects how many verses mention them.
Writing prophets are derived from authorship of a Major or Minor Prophets book in the Theographic dataset. Speaking prophets are a curated set. Dates approximate a prophet's earliest mention and are not precise ministry dates.
