Vintage Lighting Crossover Design

These c.1935 vintage wall sconce lighting fixtures, made by Lightolier, New York. show a strong leaning towards mid-century design yet they retain some of the art deco influence they evolved from.  As styles evolved and new design classes were born (or older ones revisited), you often see this type of cross-over in design. A few come to mind: from Victorian to Art Nouveau, from Art Nouveau to Arts & Crafts, from Arts & Crafts to Art Deco, from Art Deco to Mid-Century.  Most often, styles did not just pop onto the design scene and from that date onward only that style was in vogue. No, there was a transition period where design elements from one style were incorporated into design elements of the new blossoming style. And as it is today, there was resistance to the new style, there were champions of the new style, and finally there was general acceptance of the new style as manufacturers sought to fill the new demand as quickly and inexpensively as possible. That meant incorporating some of the old tried and true design elements into the new style.
This is one reason vintage lighting fixtures classified as "Art Deco" go so seamlessly into Bungalows and "Craftsman" style homes.
Be aware of the different styles in antique lighting, just don't be too hungup on trying to classify them into a box as sometimes that results in just that: a box, with not too much light or life.
