sanguis, sanguinis, m., blood, race, stock, family

Aeneid, 1.19-20, 'Progeniem sed enim Troiano a sanguine duci/audierat Tyrias olim quae verteret arces' (for she (Juno) had heard that a race would be drawn from Trojan blood which would some day overturn the Tyrian citadel). cf. sanguisuga, blood-sucker, leech. Eng. sanguine, of the color of blood; having the temperament and ruddy complexion formerly thought to be characteristic of a person dominated by this humor; passionate; cheerfully confident; optimistic. P. B. Shelley, The Cloud, l. 31-38. The sanguine sunrise, with his meteor eyes,/And his burning plumes outspread,/Leaps on the back of my sailing rack,/When the morning star shines dead,/ As on the jag of a mountain crag,/Which an earthquake rocks and swings,/An eagle alit one moment may sit/In the light of its golden wings.
