While Jeremiah Theus was a prolific portrait painter (large oil on canvas portraits) in colonial Charleston, his miniatures on ivory are extremely rare, only four are known. Born in Switzerland and likely trained in Europe, Theus brought his artistic skills to Charleston and painted the Lowcountry's elite. Isaac Mazyck II was one of nine original commissioners to build St. Michael's church. In 1751, St. Philip's Anglican church decided to build a second parish and split the population to ease church crowds. St. Philip's would serve parishioners living north of Broad Street and St. Michael's parishioners were those living south of Broad Street.
