How to use Crosslight

Back to the map

Each arc is a cross-reference — a conceptual link between two verses. Color is distance. Lean in, and smaller details appear.

In 2007 Pastor Christoph Römhild assembled a digital set of King James cross-references — conceptual links between verses, people, places, and phrases. With Chris Harrison he drew all 63,779 of them as a rainbow of arcs. Color is distance: short local echoes sit near the bars in magenta; the longest spans, Genesis to Revelation, rise in green. Jordan Peterson later called the Bible the first hyperlinked book. Crosslight makes that map interactive.

@SaintJerm

I’m Bible Thumper. SaintJerm is from my name, Jeremy — Jerm for short. It just stuck. I’ve had it for many years. I make cartoons, glitch pictures, and Scripture art from the van. I wanted Chris Harrison’s rainbow of 63,779 cross-references to be something you can actually follow: tap a strand, read both verses, and see why they speak to each other.

How to read the picture

The bars

The row along the bottom is every chapter, Genesis 1 at the left. Bar height is the number of verses. The tallest spike is Psalm 119. Genesis and Matthew are the pale bars that open each testament.

The arcs

There are 63,779 of them. Hover or tap an arc to see the two verses it joins. Click a book name or a chapter bar to open that place in the King James text.

The rainbow

Short links stay low and magenta. Mid-range links turn cyan. The longest spans — Genesis speaking to Revelation — rise in green.

  • Nearby echo
  • A few books apart
  • Across the whole canon

Six things you can do

  1. 01

    Click a book

    The names along the bottom are the sixty-six books. Tap one, or a chapter bar, to open it.

    Follow an arc

    Click a colored curve. The dock shows both verses and every other link at that place.

    Lean in

    Scroll or pinch to zoom. Drag to pan. Double-tap the map to see the whole Bible again.

    Keep a note, send a verse

    Write a thought in the dock. Open Notes to review them. Email a verse or a connection from the envelope.

Start with a famous thread

These pairs are easy to find. Open one and the map leans in on that span.

Type, language, and light

Settings change dark and light, eight languages, typeface and size, scripture translation, and how dense the arcs appear. Your choices stay on this device.
