1793—probably ultimately after post-classical Latin ‘mille viae ducunt homines per saecula Romam…’ (‘a thousand roads lead for ever to Rome the men…’)—the metaphor occurred in A Treatise on the Astrolabe (ca 1391), by Geoffrey Chaucer
‘the lion’s share’ (UK, 1790)—calque of French ‘le partage du lion’ (now ‘la part du lion’)—from ‘The Heifer, the She-Goat, and the Ewe, in partnership with the Lion’, a fable by Jean de La Fontaine (1621-95)
