Tabitha Vevers and Daniel Ranalli remember talking to each other 25 years ago at Long Point Gallery, the now-gone artist-run space on the top floor at 494 Commercial St. in Provincetown. It was the last opening of the season, and though they had met before, this was their first real encounter. They married a few years later on the waterfront deck of Robert Motherwell’s printmaking studio in the far East End.

Art has remained one of the many threads binding their lives together, along with concern for the environment and the perils of climate change. This summer, they both have exhibitions on the Outer Cape.

Vevers’s recent painting Harmony Wind Turbines depicts a landscape marked by an effort to move from a petroleum-based culture to one harnessing the power of wind. The spindle-like forms of the turbines also suggest batons used by orchestra conductors, or simple abstract shapes in the land. “The work is still very personal and very much me,” Vevers says, “but less about the figure and more about the environment.”

Her “Hope” and “Offerings” series, also non-figurative, are inspired by Provincetown’s large jetty rocks and smaller “luck rocks,” gray beach stones with white bands found on Herring Cove. Of her painting Desert Petrichor, she says, “For me it’s almost full-circle, a moving back to abstraction, and a fascination with roads: that dark, blackish color, and the smell of earth and asphalt when rain falls after a long drought.

“A natural part of aging is looking back but also looking forward,” Vevers says. She is overseeing construction of a studio addition in Wellfleet, where the couple lives. They also live part of the year in Tucson. “What’s great about our winter move is starting a new life, with ideas for new work,” Vevers says, which includes her turn toward abstract landscapes. Many of these works will be on view this month in her exhibition “East — West” at Berta Walker Gallery.

Ranalli responded to the Southwest and its wildfires in a more figurative series called “The Garden (Eden).” The photo montages feature figures from art history that he depicts as Adam and Eve, complete with a red apple and a snake. He places the figures in his version of the proverbial garden, now on fire. In 2007, Vevers also created a series based on her vision of a future Eden. These dystopian paintings with their androgynous, humanoid beings likewise warn of planetary perils.

Ranalli exhibits widely in the Boston area and recently had two shows in Tucson. He hasn’t exhibited in Provincetown since the days of artStrand and before that in the second-floor DNA gallery, adjacent to the East End Tennis Club, where both he and Vevers showed their work. “The Cape doesn’t really love photography,” Ranalli says. “And my work is a little bit on the conceptual side.”

Ranalli’s “Zen Dunes” series, much of it created on Provincetown’s back shore with assistance from Vevers, is on view at the Wellfleet Adult Community Center’s Great Pond Gallery through August.

This series “started a couple of years ago when we would visit the dunes, staying in Thalassa, one of many shacks without water, plumbing, or electricity,” says Ranalli. “I’d wander around, figuring out what I wanted to do. Everyone took pretty pictures, and I didn’t want to do that. There was one point when I was looking at this sort of bowl in the dunes, a hollow area, and I decided to sweep it clean, as a meditative act. Once it was cleaned of footprints, I found a rake and started raking the sand.”

A film on Ranalli’s website reveals his mark-making process: he rakes an expanding series of loops where the wind has left a hollow in the sand. Eventually, he decided to photograph his sand drawings using a large-format camera.

“There are a million things you could do wrong,” he says. “There we were in the shack changing film out by getting it into a big black sack” without letting light creep in.

Ranalli, who retired as a professor of arts administration at Boston University in 2015, is familiar with the presence of sand in many of the paintings of Tony Vevers, Tabitha’s father. “I always made this joke that Tabitha’s father was an art history professor, he had a mustache, and he worked with sand, so maybe she married her father,” he says. “But it all worked out.”

“Art is our religion,” Vevers wrote in a tribute to her father, who died in 2008. This devotion reverberates in her relationship with Ranalli.

“Being married to an artist is a very powerful connection and something I value enormously,” says Ranalli. “You try to help each other’s careers and help each other with ideas. It’s kind of a magical mystery tour, and you don’t know what’s coming next.”
