Terms of use

A cultural reference site. We gather fact sheets for works and artists with public-domain reproductions verified on Wikimedia Commons, timelines of art movements, catalogues of literature whose copyright has expired, algorithm-generated maths and technology pages, and material from religious and astrological tradition treated as reference.

We do not sell art, appraise art, authenticate anything or broker auctions, and we have no relationship with any museum, gallery, church or publisher. Nobody pays to have a page here.

A work enters the public domain when the author’s term of protection expires, and from then on anyone may reproduce it. That applies to the work, not automatically to a photograph of it: a modern photo of a sculpture can carry the photographer’s own copyright. So we check the licence of each file before publishing, and an artist whose work is still protected appears here in text only, never in an image.

The public domain does not require attribution. We credit anyway, and not out of politeness: on an art site, the author’s name, the collection that holds the work and the link to the file are part of the information you came for. If our credit line is wrong, we fix it.

The verse, psalm, devotional and saint-of-the-day pages describe a tradition and quote texts whose copyright has expired — the 1611 King James Version, the 1917 Tradução Brasileira, the 1909 Reina-Valera, the 1910 Segond, the 1912 Lutherbibel, Diodati. They are not a religious service, they do not speak for any church, and they do not replace guidance from whoever leads your community of faith.

The pages on signs, compatibility and numbers describe what astrological and esoteric tradition claims. We do not present that as verifiable fact, we do not predict events, we do not promise outcomes and we give no advice about health, money, work or relationships. When a page says "tradition associates", that is exactly what it means.

Birth dates, year of creation, medium and current collection come from public sources and museum catalogues, with no recalculation by us. For very old works the holding institution itself sometimes records a range ("c. 1500") rather than a year, and in those cases the page shows the range instead of inventing precision.

The maths pages — multiplication chart, Roman numerals, primes — are computed by algorithm at build time, not copied from a table. If you find a discrepancy in any figure, write to us: that is the kind of error we fix the same day.

Read it, print it, quote it and send the link to anyone. You may freely use the public-domain reproductions, but take the file from the source: under each image there is a link to the file on Wikimedia Commons, with the original resolution and the exact licence of that reproduction. Our copy is downsized so the page loads fast.

You may not copy the whole site or scrape the pages in bulk to build a lookalike. The works are public; the written text, the organisation, the fact sheets and the translations are ours.

The site is paid for by advertising. Ads are served by third parties and never decide what goes into the site: there is no "sponsored" artwork and no text traded for money. Pages that admit they lack the information stay online but carry no ads.

Links to museums, Wikimedia Commons, Project Gutenberg, Wikisource and digital archives lead off this site, and what happens there is not under our control.

These terms can change when the site changes. The version that applies is the one published on this page.

Any dispute follows Brazilian law, that being the country of the person responsible for the site.
