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 summarizes the source inventory (green=canonical text, teal=edition reference, amber=partial, grey=absent/fragmentary). Click a cell for loci & passages.
Literary attribution — edges record how a surviving author names and treats a supplier; they do not verify direct historical communication. Edge colour = reception category (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.
问题：若干希腊罗马作品如何保存、限定并再利用未充分证实的远方信息？转述、来源归属与采信须分别判断；重复出现的报告未必彼此独立。化外是相对于作者或读者的位置而言，当地人未必陌生。琉善的讽刺、斯特拉波的评价与托勒密的数值处理，各有语境。现代动物指认与地图路线属于待检验的解释，不能反向证明古代叙述。Question: how did selected Greek and Roman works preserve, qualify and reuse uncertain information about distant places? Reporting, naming a supplier and assenting require separate assessment; repeated accounts may depend on one another. The beyond is relative to writers and readers, while residents may know it well. Lucian’s satire, Strabo’s judgments and Ptolemy’s numerical transformations have distinct contexts. Modern animal identifications and mapped routes remain interpretations to be tested, rather than retrospective proof of ancient reports.
