Each marker is an expedition on a time axis (note the long gap after Hatshepsut, 15th c. BC). Colour = exchange system. Click to inspect · scroll sideways if labels run off the edge.
Places as nodes (size = how many routes touch them), voyage-legs as edges. Hubs and gateways emerge (Pillars, Gades, Carthage, Myos Hormos). Drag nodes; click to inspect.
How lost/embedded explorers survive inside host authors. Left = the lost voice; right = the surviving mediator; link colour = the mediator's stance. Click a link for the passage.
Explorer × ancient author. Cell colour = whether litdat holds the text (green=full text, teal=PDF, amber=partial, grey=absent/fragmentary). Click a cell for loci & passages.
Transmission — each lost explorer-text survives inside a host author; edge colour = how the host treats it (relay / relay-doubt / refute / sever). ○ explorer · ▢ host · ◇ excerptor (Photios) · ✶ meta-critic (Lucian). Click a node to see every text it touches; ⚡ lights the irony chain.
Credibility — each dot is one host reading one explorer. Across: eye-witness (autopsy) → hearsay → marvel. Down: believed → doubted → refuted/severed. The paradox (◎): Patrocles' autopsy of the Caspian was factually WRONG while Herodotus' armchair guess was right — autopsy ≠ truth. Click a dot to read the passage.
