Folio from the "Qur'an of `Umar Aqta'

Note how the Prussian blue sits in the wave's trough versus its crest — later Hokusai impressions stabilize this gradient, but early pulls like this one still feel like the pigment is being tested against the page.

The cover of Debussy's 1905 Durand edition of La Mer reproduces this print at the composer's request. A cross-medium lineage worth branching into its own layer.

Cross-impression XRF of this series (see descendant analysis) supports distinct pulls over the run — not a single uniform batch, but a recarved block drifting as it wore.
