Origin: 1580–90; < Italianminiatura miniature painting < Medieval Latinminiātūra, equivalent to miniāt(us) (see miniate) + -ūra-ure; sense development perhaps influenced by Latin base min- (see mini-, minor)
1586 (n.) "a reduced image," from It. miniatura "manuscript illumination or small picture," from pp. of miniare "to illuminate a manuscript," from L. miniare "to paint red," from minium "red lead," used in ancient times to make red ink. Extended sense of "small" (adj.) is first attested 1714, because
pictures in medieval manuscripts were small, infl. by L. min-, root expressing smallness (minor, minimus, minutus, etc.).
