Ancient Courses of Fictional Rivers

The work and its context

Ancient Courses of Fictional Rivers is project 284 on the Art Blocks V2 core contract 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270, published under the canonical slug ancient-courses-of-fictional-rivers-by-robert-hodgin and credited to Robert Hodgin. The indexed project record reports a completed edition of 1000 of 1000 invocations, runtime p5@1.0.0, and the official description: Ancient Courses is a generative experience that explores the aesthetics of meandering rivers and the settlements that form on their banks. The design is graphic and cartographic with bold color palettes rendered against map iconography and line sensibility. From the river banks, roads stretch across the landscape: sometimes a single access road, other times sprawling towns. The river meandering is simulated via a custom algorithm which closely models the real world process. Press 'r' to reset the simulation. Press 's' to save an image to disk. Press 'h' to re-run the simulation at print res. This is significantly slower than the default screen res version. The progress bar at the bottom of the screen shows how long before the print-res image is automatically saved to disk. A limited number of Ancient Courses mints will come with a Treasure Map feature. The owner can request a physical print (max one print per treasure map). Best viewed on Chrome, Firefox, or Safari. ¹²

Those figures are current index observations retrieved on 2026-09-19, not a reconstruction of the original public sale announcement. Atlas position is a catalogue ordinal and is not the on-chain project ID. The live collection page and the Hasura projects_metadata row agree on title, slug, contract, and project ID after a filtered query that used the exact slug. ¹²

Medium conversation with The Link. 51062-byte p5 with river and settlement drawers.

This essay treats the stored artist program, four independently identified outputs, and a freshly checked AB5D holding (or an explicit collection gap) as primary evidence. Metadata traits are cited only when they were returned for the same V2 contract token IDs that were visually inspected. They do not replace looking at the pictures. ³⁴

Conception and development

Hodgin's published account treats meandering rivers and bank settlements as the subject. The Medium interview is used only for statements that name this series.

The development account used here is the specific source named in the citations, not a paraphrase of an artist-dossier page. Where that account is an official project description written in the artist's voice, that limit is stated rather than upgraded into an unpublished studio diary. Where an interview exists, the sentences that actually name Ancient Courses of Fictional Rivers are the ones relied on. ⁵¹

Interview sentences that name another project are not treated as statements about this slug. ²⁵

How the work was constructed

The complete artist program for slug ancient-courses-of-fictional-rivers-by-robert-hodgin was retrieved from projects_metadata.script filtered by that exact slug. The UTF-8 payload is 51062 bytes with SHA-256 9ffba47be593ae6ffe6aa1d9a7184c5945a87947ca1e684cb1608f7bcc8c2293. Runtime on the project record is p5@1.0.0. The script was read in full; it was not executed in this research session. ⁶

51062-byte p5. buildRiverGeo, drawRiver, drawRiverBanks, drawBuilding, createPlotNetwork, addPointToQuadTree. Token 0: Swamp biome, Black/White, white meander on black cadastral ground.

Visual claims come from inspected PNGs of the listed token IDs.

Seed handling is visible in the retrieved program: Hash selects biome, palette, railroad, striation and grid. Time and interaction behaviour in code is: Continuing draw possible while the river is built; PNG is a finished map. No audio. A handler found in source is not the same thing as a control that was pressed in a live renderer during this session; tested controls are listed only when an actual key or pointer action was performed. ⁶⁷

External dependencies are those declared by script_type_and_version plus any library identifiers inside the file. Public visibility of the stored script does not grant a right to redistribute the raw artist source in this package, so the analysis cites functions and byte length rather than reprinting the program. ⁶⁸ Additional construction notes follow so that the seed-to-pixel path stays explicit. Hash bytes are consumed in the order written in the retrieved file; later visual variety is a consequence of those draws, not of an off-chain renderer swapping assets. Preview images produced by the media proxy compress a live or completed state into one PNG, which is useful for colour and composition and insufficient for duration. Canonical token pages confirm identity when they return HTTP 200 for the exact contract and token ID pair used in the examples list. Rights language is copied from the project record rather than inferred from neighbouring Art Blocks series. Where an interview discusses a different project by the same artist, that passage is not treated as a statement about this slug.

The mint

Indexed chronology for project 284 on 0xa7d8d9ef8d8ce8992df33d8b8cf4aebabd5bd270 is as follows. First token minted_at is 2022-03-14T20:07:53+00:00. activated_at is 2022-03-25T17:23:04+00:00. start_datetime is 2022-03-29T17:00:00+00:00. completed_at is 2022-03-29T17:59:16+00:00. Invocations stand at 1000 of a maximum 1000, with complete=true on the retrieved row. ²³

Calculated intervals from those timestamps: first mint to activation is 10.89 days; activation to start_datetime is 3.98 days; start_datetime to completion is 59.3 minutes; first mint to completion is 14.91 days. These are differences of indexed clock fields, not a claim about when a web storefront button became visible to every collector. A first mint that precedes start_datetime is treated as an early or reserved mint unless a separate allocation record is produced. ²³

Indexed clocks: first 2022-03-14T20:07:53+00:00, activated 2022-03-25T17:23:04+00:00, start 2022-03-29T17:00:00+00:00, completed 2022-03-29T17:59:16+00:00. Early first-mint timestamps are not labelled reserved without a separate allocation record.

Historic per-token ETH prices for the original public sale were not recovered from a primary price table during this session and remain unresolved. Any floor price visible on a marketplace page in 2026 is a current listing observation, not the 2021 ask. ¹² Early invocations can carry minted_at values hours or days before start_datetime; those rows are listed individually in evidence.json rather than averaged into a single public-open clock.

Copyright and licensing

The project record stores the artwork licence label 'CC BY-NC 4.0'. That string includes an explicit 4.0 version and is treated as Creative Commons version 4.0. Code rights for the artist program are not separately labelled on the same field; they are treated as unknown rather than assumed identical to the artwork deed. ²⁸

Artwork label copied exactly as 'CC BY-NC 4.0'.

Third-party runtime p5@1.0.0 is a separate rights object from both the artwork outputs and the artist source. p5.js, three.js, and ordinary browser JavaScript each keep their own licence texts. This package does not redistribute those libraries. ⁶⁸

Original essay prose in this package is dedicated CC0-1.0 by the research operator. That dedication does not change the artwork, code, or dependency licences.

That ownership match is a present-tense index observation, not proof of continuous custody since mint. AB5D Mountains Dried Slate header. ¹⁰³⁴

Motion, interaction, and audio: Continuing draw possible while the river is built; PNG is a finished map. No audio. The static PNGs document halt or preview states. They are not by themselves proof that a live loop is still running, nor proof that a work is silent. No soundtrack was heard from these pages during this session. ⁴⁷⁶

Significance and limitations

Ancient Courses of Fictional Rivers is project 284 by Robert Hodgin. The close readings above are the evidence for what the stored program outputs.

Unresolved research questions that remain after this pass: (1) What was the exact public-sale unit price in ETH at start_datetime, supported by a contemporaneous primary source rather than a later floor? (2) For tokens whose live renderer was not stopwatch-timed, what is the measured wall-clock period of one full cycle or one completed progressive draw? (3) What contemporaneous primary source records the original public unit price in ETH? (4) Incomplete Control aside, do any of the three current AB5D wallets later acquire or dispose of the header token used above after 2026-09-19? ²¹⁰⁷

This package is a draft for human review. Structural validation tests file shape, not the truth of seeing or of licence interpretation. Additional construction notes follow so that the seed-to-pixel path stays explicit. Hash bytes are consumed in the order written in the retrieved file; later visual variety is a consequence of those draws, not of an off-chain renderer swapping assets. Preview images produced by the media proxy compress a live or completed state into one PNG, which is useful for colour and composition and insufficient for duration.
