How it works

Type the title of a book. Literary Lineage asks Claude, Anthropic's model, to act as a literary historian and build the family tree of influence behind it: the works the author is known to have read and borrowed from, the works those drew on in turn, and so on, until each line reaches the oldest surviving literature of its tradition or stops for a stated reason.

The tree is checked before it is shown: every influence must run from an older work to a newer one, every work must connect back to the book you asked about, and a tree that is too thin or never reaches antiquity is thrown out and tried again. Then it is kept, so the next reader who asks about the same book sees the same tree at once.

Reading a tree

Time runs down the page. Each work's page says what it handed down to the works above it and where it came from itself. Every link is marked by kind (a direct source, a structural model, a stylistic influence, a thematic kinship, or a disputed connection) and by how well it is documented. Where scholars disagree, the tree says so rather than pretending.

You can step through every work newest to oldest, or pick one influence and follow that single thread down to antiquity.

What to trust

These trees are written by a language model from the scholarship it has read. They are good at the well-trodden routes and worth checking on the obscure ones. Dates are the usual estimates; for ancient and medieval works they are approximate by nature.

The links to Amazon

Each work links to an Amazon search for its title and author, so you land on the editions in print rather than one edition we chose for you. As an Amazon Associate, Literary Lineage earns from qualifying purchases; it is how the site pays for the model that writes the trees.
