NAIVETE', f. [French.] Simplicity; ingenuoufnefs. 
—Is not that naivete and good humour, which his admirers 
celebrate in him, owing to this, that he has continued all 
his days an infant, but one that unhappily has been taught 
to read and write? Gray's Lett, to Beattie. 
Of the import of this word, having no correfponding 
one in our language, it is not eafy to give a precife idea. 
It always exprefles a difcovery of character. M. Mar- 
montel, who has given the belt account of it, explains it 
thus: “That fort of amiable ingenuity, or undifg.uifed 
opennefs, which feems to give us fomc degree of fuperiority 
over the perfon who fhows it: a certain infantine fim- 
plicity, which we love in our hearts, but which difplays 
fome features of the character that we think we could 
have art to hide; and which, therefore, always leads us 
to fmile at the perfon who difcovers this character.” 
NAI'WINCK, or Naiwyncx (Henry), a landfcape- 
engraver of confiderable merit, who flourifhed at Utrecht 
in the 17th century. He painted alfo; and in the ca¬ 
binets of the connoifieurs of Holland are drawings in 
Indian-ink by this artift, which are performed with 
mu.ch care, and alfo with feeling and tafte. His reputa¬ 
tion, however, was chiefly founded on his etching of 
landfcape. His works are faithful reprefentations of 
Nature; and the feeling and delicacy which every-wkere 
accompanies his etching-needle, has occafioned his prints 
to be much fought after both by artifts and. colleftors. 
He always etched from his own pictures or drawings, and 
very rarely introduced any figures into his landfcapes.
