From Middle English primum mobile (“outermost celestial sphere causing other spheres to move”), borrowed from Late Latin primum mobile (literally “first mover”), from Latin prīmum (“first; at first”) (adverbial accusative of prīmus (“first”)) + mōbile (from mōbilis (“mobile, movable”)). The Latin term is a calque of Arabic مُحَرِّك أَوَّل (muḥarrik ʾawwal, “first mover”). The English term is cognate with Ancient Greek τὸ πρῶτον κινῆσαν (tò prôton kinêsan, “prime mover”) (and compare πρώτη κίνησις (prṓtē kínēsis, “first motion”)).

- But as there is a double motion of the stars, that is, under the primum mobile, and round the world, by both which, as we have said, they influence, we must consequently suppose, that the significators rule over things subjected to them by this twofold (or double) motion, to wit, under the primum mobile, and round the world.

- The American poet Ange Mlinko's fifth book is "Distant Mandate" (Farrar, Straus & Giroux). Her title, borrowing a phrase from the writer László Krasznahorkai, refers to art's primum mobile, its primordial first domino. The drive to create art is a "mandate" so ancient that it should probably by now have expired, and yet when it arrives, still, it is always in a hurry.
