Nevermet, here is a start on some of the greco-roman symbols. Columns in the style of the Palace of Knossos. 8 symbols in various orientations that should work in Perspectives as free standing symbols. Enjoy.

@Nevermet, I cranked these out as prototypes in Bryce. I'd like to see more Perspectives styles but I can see why there are so few. The symbols aren't that difficult to produce as 3d models but it is devilish hard for me to wrap my old brain around the proper orientation angles for the symbols.

Just to get the ball rolling, these are free for private and commercial use in maps but not for re-sale as stand-alone symbol(s)
