Okay, lemme see if I've got this right...
Neoclassicism -
Started with the Renaissance in other areas; but didn't reach furniture until about the start of the 19th century. Once there, however, it stuck around until at least the early 20th century. (If I'm not mistaken, Revival, Empire, Jacobean, Chippendale, Queen Anne are all sub-groups under the Neoclassical heading.) Neoclassicism may be showing up in my bed's simple lines and clean curves.
Victorian -
1840-something to 1905-ish. Heavy, highly ornamented, intricately detailed. Someone who didn't particularly care for this style might say that its worst excesses seem to be what happened when mass production hit Rococo. Someone who didn't particularly care for this style but did own my bed might admit to seeing a possible Victorian influence in a slight heaviness to the bed's overall shape, but that's about as far as she'd be willing to go.
Arts & Crafts style -
Started mid-19th century, was partially subsumed into Art Nouveau in the late 19th & early 20th centuries, and then largely surpassed by Art Deco in the 1920's - 1940's. What I'll call the "graceful utilitarianism" of my bed's overall design would be in keeping with the "form follows function" principle underlying the entire Arts & Crafts Movement.
Art Nouveau -
Started late 19th century, continued into 1920's or so. My bed's gracefully scrolling legs & feet seem to reflect the "whiplash" line characteristic of Art Nouveau.
Art Deco -
1920's through 1940's. Neoclassicism for the machine/atomic age, often influenced by then-freshly-(re)discovered Egyptian antiquities. The simple, "streamlined' lines of my bed could Neoclassicism showing up in Art Deco.
So, my bed show Neoclassical, Arts &Crafts, & Art Nouveau influences. I think I'll stick to calling the bed's style "post-Nouveau," at least to myself, not least because I like the oxymoron-wordplay of it.
