An early Florentine Renaissance masterwork, a large important relief carved marble, an original from about 1465-1480 and from the hand of a master. Forty years here, an old estate tag had suggested the author as Benedetto da Maiano, (1442-1497). I see the possibility, or by yet, even possibly one better. I can simply guarantee its vintage, its very fine condition and the fact that it hasn't been seen on any market for about a century, if ever. Never shown or inquired about, I leave its most likely easy authorship factor up to you. I can also guarantee the starting bid will absolutely leave tremendous potential up-side leverage for any value buyer. Of white marble, a particularly large and thick slab, the carving deep and profusely undercut, I see potential for the possibility of Andrea del Verrocchio. This piece was carved and polished for a major metropolitan cathedral. I've never more than dusted it off and it remains in about the same fine condition as when crafted. Among the tens of thousands of things here, it is one of the noticeable few that will be missed. Of course it is rather heavy, so, to reiterate, some days, post sale, we expect to have a delivery van with a trip to one or two places in and near N.Y. City, we'll figure it out for the money saving convenience of regional buyers of the large and heavy, .. or, for whatever else of any quantity. Otherwise, we'll crate and find safe and reasonable shipping. Last image down shows a plaster cast of a similar relief by da Maiano that is in the Victoria & Albert Museum. Many world class museums lack such example as this. I can promise another thing, it is one heck of a lot more beautiful and impressive that these photos tend to show. I'm sure you realize that unlike the far more common works in terracotta, the marbles were singular, one-off carvings. 25"height, 20" length, 3" thickness.
