COBB, Sylvanus, clergyman, born in Norway; Maine, in July, 1799 ; died in East Boston, 31 October, 1866. In 1828 he was settled over Universalist churches at Malden and Waltham, Massachusetts, and in 1838 took charge of the "Christian Freeman," which he edited for more than twenty years. He was for many years a leader in the anti-slavery and temperance movements. Dr. Cobb's published works include "The New Testament, with Explanatory Notes" (Boston, 1864); "Compend of Divinity" and "Discussions."--His son, Sylvanus, author, born in Waterville, Maine, in 1823; died in Hyde Park, Massachusetts, 20 July, 1887, was editor and publisher of a paper called "The Rechabite," edited the " New England Washingtonian," and was a principal contributor to "Gleason's Pictorial," " Flag of Our Union," and the New York "Ledger." He published " The Autobiography of Rev. Sylvanus Cobb," with a memoir (Boston, 1867), and numerous tales, including "The King's Talisman" (Hartford, 1851): "The Patriot Cruiser" (New York, 1859)" and " Ben Hamed" (Boston, 1864).--Another son, Cyrus, artist, born in Malden, Massachusetts, 6 August, 1834, was graduated at Lyman school, East Boston, in 1848, and afterward studied the higher mathematics and classics. He and his twin brother Darius studied art together, and refused opportunities for European study, wishing to have no master but nature. While perfecting themselves in art the brothers retired together at midnight and rose before sunrise, and they have since been closely identified in their work. At this time they practiced mental mathematical calculation, as an exercise to prepare the mind for future work, and attained great proficiency, for example, in multiplying large numbers mentally. Cyrus began the study of law in 1869, to enable himself and his brother to bring out their large historical works. He was graduated at the Boston University law-school in1873, and practiced till 1879, when he resumed his art work. Among his sculptures are a bust of Be Po Shillaber (1867), the Cambridge Soldiers' Monument (1869), an heroic bas-relief of Prospero and Miranda (1883), heroic statue of Abbott Lawrence (1885-'6), " Ancient Celtic Bard contemplating the Future Woes and Dawning Light of Ireland" (1886), and a bust of Theodore Parker (1886). His paintings include "Jesus Condemned," containing about thirty figures, those in the foreground of colossal size (1879); " Warren at the Old South" (1880); and portraits of Dr. A. P. Peabody and Dr. J. Appleton. Mr. Cobb has paid much attention to music, is a member of the Boylston club, and has a tenor voice of great compass. Both the brothers have led orchestras, and in later years have directed choruses. Mr. Cobb has written, besides other poems, thirty sonnets on the "Masters of Art," which appeared in the Boston " Transcript," and are to be published in book-form. Both the brothers served in the civil war in the 44th Massachusetts regiment. To set forth the aim and purpose of the Grand Army of the Republic, Cyrus has written a novel, "Veteran of the Grand Army" (Boston, 1870).--Cyrus's twin brother, Darius, born in Malden, Massachusetts, 6 August, 1834, studied with his brother at the same schools, and has painted per-traits, landscapes, and figure-pieces. The latter include "Judas in the Potter's Field" and " King Lear" (1877); "Christ before Pilate," his chief work, which has been highly praised, and which has been engraved (1878);"For Their Sakes," a temperance painting (1879); and "Washington on Dorchester Heights" (1880). In conjunction with Cyrus he has painted a rendering of Leonardo da Vinci's "Last Supper," which has been pronounced the best ever made. These are all large exhibition pictures, varying from six to nine feet in length. His portraits include that of Collector Simmons, in the Boston custom-house (1875), and one of Rufus Choate, purchased by the Suffolk bar in 1877. Those of Governor Andrew (1868) and Prof. Agassiz (1883) are owned by Harvard. Among other per-traits by his hand is one of Charles Sumner, a two-thirds length of Henry Wilson, bought in 1876 by his native town, and those of Cyrus and Sylva-nus Cobb, Jr., sent to the Centennial exhibition. Among his landscapes is "Back Bay Lands." Mr. Cobb has assisted his brother Cyrus in his musical work, has lectured on art before lyceums and Colleges, and was art editor of the Boston "Traveller" for several years. He has written poems on art and nature, and numerous essays in periodicals, not yet published in book-form, and also has an art novel in manuscript.
