History and context

Copán's Hieroglyphic Stairway displays more than 1,800 glyphs and portraits of rulers, the longest known continuous Maya inscription. Ascending it meant walking through a dynastic history constructed to legitimise the present.

When it was reassembled at the end of the nineteenth and beginning of the twentieth centuries, much of the writing could not yet be read. Blocks out of their original position turned the monument into a puzzle: today epigraphy recovers sequences, but not all the text can be restored with equal certainty.

More than 1,800 glyphs turned the ascent into a walk through a genealogy of rulers. Stone, portrait and writing made the visitor literally tread a dynastic version of the past.

Many blocks were repositioned when the writing could not yet be read, so part of the original sequence was lost. Epigraphy recovers episodes, but a digital reconstruction must grade the secure and uncertain stretches.

Evidence and interpretation

Documented fact: UNESCO records a stairway of more than 1,800 glyphs, initiated in the seventh century and expanded by the Copán dynasty. Interpretation and caution: the narrative is court history and some passages remain uncertain due to erosion and block relocation.

Scanning without losing the old photographs

Between 2008 and 2012, the blocks and sculptures of the Hieroglyphic Stairway were digitised in three dimensions. The Peabody combines these models with 19th-century glass photographic negatives, which preserve details eroded since then. A 1:10 scale printed model allows testing the reading order on a table without handling the originals. The first version of the stairway commemorated Ruler 12 and his burial; an extension was dedicated in 756. Thus, the reconstruction investigates both a disordered text and the ancient decisions that caused it to grow.
