Impenetrable: Eugenio Espinoza's installation mixes the disciplines of painting, sculpture, and conceptual art. Transforming the conceptual standard and painting's historic monumentality with lots of canvas, wood, and the systematic application of black paint and wit, Espinoza revisits his own art history and heady era of international Geometric Abstraction. The Venezuela native has constructed a horizontal, waist-high, paintinglike grid structure that completely dominates two conjoined spaces in Locust Projects. Kathleen Hudspeth Through October 29. Locust Projects, 105 NW 23rd St., Miami; 305-576-8570.
Una Tal Juana: Ninth-century Englishman John Anglicus was a brilliant scholar who lectured at the Trivum in Rome before becoming a cardinal and eventually pope in 853 A.D. Two years later, riding from St. Peter to the Lateran, he stopped to give birth to a child. Pope John VIII was really Pope Joan. According to legend, after learning the truth, the people of Rome dragged her behind a horse and then stoned mother and baby to death. Colombian artist Flora Cohen transforms this outrageous story into a beautiful narrative-exhibit with a mixture of humor, perversion, and gloom. Enjoy Cohen's delicately drawn quizzical black-and-white panels, and learn more about a certain aversion, popular among Joan's court following, to beards. Alfredo Triff Through October 15. Bernice Steinbaum Gallery, 3550 N. Miami Ave., Miami; 305-573-2700.
