The best Greek mythology family tree tools in 2026

MythBranch combines a whole-atlas view with era pages, individual family-tree profiles, downloadable gallery editions, an embeddable widget, and a public knowledge graph. The current evidence release contains 175 controlled entities, 210 assertions, 27 source records, and 11 explicitly labeled variants. Greek and Roman figures can be modeled separately rather than reduced to translation pairs.

Choose it when

You want one route from visual orientation to profile-level explanation, source assertions, print assets, and machine-readable data.

Important limitation

The knowledge graph is an alpha release. Its registry is broader than its passage-level source ledger, and many indexed figures do not yet have fully reviewed public profiles.

Mythoskolis takes the opposite visual approach from a giant global tree. Its HoloGraph centers one entity and arranges the nearby parents, consorts, children, and siblings around that focus. The advanced mode adds alternative relations, uncertain ties, sources, and—in documented cases—clickable excerpts. This local neighborhood model is especially readable on dense branches.

Choose it when

You want to keep recentering the graph and follow a figure through genealogy, entity sheets, and connected stories.

Important limitation

It intentionally does not present one complete global tree, so it is less suited to a poster-like overview of the whole mythic system.

Theoi offers summary charts, a genealogy based on Hesiod's Theogony, Homeric charts, and an eight-part detailed series covering primordial gods, the children of Night, Titans, sea gods, monsters, Olympians, Oceanids, rivers, and nymphs. Names link into an extensive encyclopedia with classical quotations and images of ancient art.

Choose it when

You want a broad divine reference chart and quick movement from a name to ancient literary quotations.

Important limitation

Theoi states that where ancient authors disagree, its main detailed chart selects the oldest and/or most popular source. That makes the chart legible, but not every disagreement remains simultaneously visible.

Canva provides a flexible whiteboard, family-tree templates, connectors, images, typography, collaboration, and design export. It is the simplest option in this list for a teacher or student who already knows which figures and relationships belong in a custom handout.

Choose it when

The design is the assignment: a classroom worksheet, presentation graphic, or visually branded chart.

Important limitation

Canva does not verify Greek mythology. Every name, relationship, source note, and variant must be researched and entered by the creator.

Lucidchart is useful when the tree must remain editable as a diagram. Its templates, shapes, connectors, images, and collaborative workspace make it easier to reorganize a complicated custom genealogy than a fixed poster editor.

Choose it when

A group needs to build, discuss, and revise a custom relationship diagram rather than consume a finished mythology atlas.

Important limitation

It supplies diagram logic, not a mythology corpus. Contradictory sources and special relations still require a data model and editorial decisions.

Perseus is foundational infrastructure for Greco-Roman digital scholarship, and the Scaife Viewer provides a modern reading environment for pre-modern texts in original languages and translation. It is where a serious reader can check what a passage actually says instead of repeating a chart's unsourced claim.

Choose it when

You need Homer, Hesiod, tragedy, mythography, Greek or Latin text, translations, and passage-level verification.

Important limitation

It is a digital library, not a family-tree interface. Readers must interpret the passage and connect it to a genealogy themselves.

ToposText joins a large clean-text library with a gazetteer and an index of ancient people and mythological figures. It is unusually valuable when genealogy intersects geography: a local cult, a hero's city, a river god, an island genealogy, or a passage tied to a specific landscape.

Choose it when

You want to move between ancient passages, named people, and mapped places in Greek history and mythology.

Important limitation

Its organizing problem is text and place, not a visual genealogy, so it supplements rather than replaces a family-tree tool.

Ancient images can preserve identities, attributes, pairings, cult contexts, and narrative scenes that do not function like a literary genealogy. The British Museum's collection search lets readers locate object records by keyword, person, place, object type, or museum number and filter for records with images.

Choose it when

You need an accession number, object date, material, findspot, curatorial description, or image-rights context for visual evidence.

Important limitation

A catalogue record documents an object. It should not automatically be treated as a comprehensive literary account or a complete family relationship.

Wikidata is a free, collaborative, multilingual knowledge base readable by humans and machines. Statements can carry references and links to external identifiers, and its structured data is released under CC0. That makes it a powerful interoperability layer for matching names across projects.

Choose it when

You need stable identifiers, multilingual labels, broad cross-domain links, open reuse, or a starting point for computational work.

Important limitation

Coverage and references vary by statement. It is a secondary, community-edited knowledge base, not a curated edition of one ancient tradition.
