The Stream of Time

Look down any year and see the whole world.

In 1871 Sebastian Adams drew every nation as a stream flowing left to right, swelling in its age of power and narrowing in decline. Read straight down a single year and you see what was happening everywhere at once: Rome and Han China as contemporaries, the Mongols and the Renaissance a few inches apart.

I love that chart and wanted to see what it could become as something you travel through instead of unroll.

One line of time, many ways in.

• The reading lineA gold line marks one year. Everything under it, across every stream, is happening at the same time.
• A living mapEach realm alive at the reading line lights up on a world map above the river.
• Tell the storyA 19-chapter guided tour, from "In the beginning" to "Today".
• Follow a threadTrace one idea, like the Silk Road or gunpowder, across centuries and the map.
• Marvels, ideas, and livesDrawn monuments, inventions, and 90+ notable people placed in time.
• Find anythingSearch a year like 1492, an event, a dynasty, or a person, and jump straight there.

Faithful to the scroll, honest about it.

1. Show a moment, not a list.

   The reading line turns the chart's best trick, seeing everything at once, into the main interaction.

2. Keep Adams's scale, but let people change it.

   Like the original, ancient centuries are compressed and recent ones stretched. "Even scale" draws every century the same width.

3. Respect the source, add context.

   The chart keeps Adams's 4004 B.C. starting point and his scripture bands, and the story says plainly where archaeology tells a longer one.

4. Guided or free, your choice.

   A story for people who want to be led, threads for the curious, and drag-to-travel for everyone else.

A side project, built with AI as a pair.

I designed and built it with Claude: assembling the timeline data, drawing the map and the monuments, and iterating on the design until it felt like a story rather than a spreadsheet. In its Claude-hosted version, an optional "fuller story" writes deeper context about any event on click; the copy here runs without it.
