Google’s Google has demonstrated a new use case for advanced multimodal AI after Gemini 3.0 Pro helped decode a long-standing historical puzzle in a 500-year-old printed manuscript. The GDELT Project experiment focused on a richly illustrated page from the Nuremberg Chronicle, a landmark work printed in 1493 that blends world history, theology, and early cartography.

At the center of the mystery were four handwritten circular notes, or roundels, added by a former owner centuries ago. Despite repeated scholarly attention, their exact meaning had remained unclear.

The historical puzzle

The Nuremberg Chronicle contains parallel timelines based on different biblical traditions. On one particular page, the printed text presents conflicting “Year of the World” dates for the birth of Abraham, drawn from the Greek Septuagint and the Hebrew Bible.

At the bottom margin of the page, a later reader drew four circles and added abbreviated Latin text with Roman numerals. While historians could identify that the notes referred to dates, they could not confidently explain how the figures related to one another or why they were written.

How Gemini 3.0 approached the problem

Researchers uploaded high-resolution images of the full page and close-up images of the four roundels into Gemini 3.0 Pro. The model was asked to transcribe the Latin text, translate it, and interpret the annotations using the printed content of the page for context.

Gemini identified the roundels as a conversion exercise rather than random marginal notes. Two circles record “Anno Mundi” dates drawn directly from the printed chronicle, while the other two convert those figures into “years before Christ.” The analysis suggests the annotator was comparing Greek and Hebrew chronological systems and translating both into a unified framework.

Why the findings matter

The interpretation proposes that the marginal notes were created by a 16th-century reader attempting to reconcile conflicting biblical chronologies. This offers the first coherent explanation that accounts for all four annotations and their numerical relationships.

Beyond the specific historical insight, the exercise highlights how multimodal AI can assist in humanities research. By combining visual reading, language translation, and contextual reasoning, Gemini 3.0 demonstrated an ability to analyze handwritten material, printed text, and historical conventions together.

Broader implications

The experiment suggests potential applications for AI in archives, libraries, and museums, particularly for interpreting marginalia, annotations, and damaged texts. While human expertise remains essential, tools like Gemini 3.0 could accelerate preliminary analysis and surface plausible hypotheses for scholars to evaluate.
