“Mothers are the necessity of invention.”

Compare: "Necessity is the mother of invention", Wycherly, Love in a Wood (1672), act iii. sc. 3.; "Art imitates Nature, and necessity is the mother of invention", Richard Franck, Northern Memoirs (written in 1658, printed in 1694); "Magister artis ingenique largitor Venter" (translated: "Hunger is the teacher of the arts and the bestower of invention"), Persius, Prolog., line 10.

“Necessity is the mother of invention.”
Commonly misattributed due to Benjamin Jowett's popular idiomatic translation (1871) of Plato's Republic, Book II, 369c as "The true creator is necessity, who is the mother of our invention." Jowett's translation is noted for injecting flowery, if not florid, language familiar to his Victorian era audience. (See "Note on the Translation", by Elizabeth Watson Scharffenberger, ed., in Republic (2005), Spark Educational Publishing, ISBN 1593080972, p. liii http://books.google.com/books?id=9FLdTCiaI_MC&pg=PR53.) Jowett himself, in Plato's Republic: The Greek Text, Vol. III "Notes", 1894, p. 82, gives a literal translation of Plato as "our need will be the real creator," without the proverbial flourish. The Greek text is: ποιήσει δὲ αὐτήν, ὡς ἔοικεν, ἡ ἡμετέρα χρεία.
