The market for Gorey books and merchandise buoys indie publishers like Pomegranate, which brings some of Gorey’s books back into print each year, and Fantagraphics, which is releasing a third edition of “The Strange Case of Edward Gorey,” a portrait by the novelist and longtime Gorey friend Alexander Theroux. Attendance has been climbing steadily at the Edward Gorey House in Yarmouth Port, Mass., and curators of the first major traveling exhibition of Gorey’s original art, “Elegant Enigmas”  originally shown at the Brandywine River Museum in Chadds Ford, Pa., and now on view at the Boston Athenaeum  have been stunned by the enthusiasm surrounding the show.

“I knew Gorey had a wide following, but I had no idea of the mania,” said David Dearinger, an Athenaeum curator, before the exhibition opened there in February. News media inquiries and calls from the public had been coming in for months, he said then, “and the show isn’t even here yet.” Since the opening, he said last month, “the response has been phenomenal.”

Opinions differ about why Gorey  whose name increasingly serves as shorthand for a postmodern twist on the gothic that crosses irony, high camp and black comedy  is casting a longer shadow these days. Mr. Handler attributes Gorey’s growing popularity partly to the sophisticated understatement of his hand-cranked world, a sensibility that stands out sharply against the exuberant vulgarity of our age of jeggings, “Bridalplasty” and “Jackass 3D.” “That worldview  that a well-timed scathing remark might shame an uncouth person into acting better  seems worthy to me,” Mr. Handler said.

Undoubtedly such romanticized visions of a more decorous, dapper past, which also inform the neo-Victorian and neo-Edwardian street styles of goths and steampunks, have as much to do with escapism as historical fact. But accurately or not, such subcultures see in Gorey’s work an invitation “to return to a time of gentility,” to quote the promoters of the annual Edwardian Ball, a celebration of Gorey.

In contrast, some fashion designers see Gorey’s anachronistic use of historical references as perfect for our age of mash-ups and remixes. The neo-Victorian couturier Kambriel, whose shows have featured Gorey-inspired sets and models reciting Gorey limericks, said that in her designs, as in Gorey’s tales, “the propriety of the past” is infused with the “playful mischief and irreverence” of the present.
