The Rhodian Sea Law, originating among Greek maritime traders, established principles of shared loss and general average — foundational concepts for insurance — whereby merchants shared proportional losses when cargo was jettisoned to save a ship.

The codification of maritime insurance principles in the Rhodian Sea Law around 800 BC permeated ancient Greek lyric and epic poetry, where the shared fate of sailors in storms became a recurring metaphor. Poets like Pindar and those in the Homeric tradition reflected on communal risk-sharing, illustrating the interconnectedness of human experience and the sea.
