There are times when it’s very clear that the weather in Europe in the late fifteenth century is not the weather in 21st century New England. This February calendar image from the Morgan Library’s Da Costa Hours (the work of Simon Bening) shows workers in a vineyard. In the foreground one man is trimming a grape vine with a knife, while just behind him a second man is tying a vine to a pole. To his left in the forefront a third worker is breaking ground with a pick axe, with a shovel ready at hand on the ground. You’ll notice that the landscape looks like early spring, with no snow in sight. In colder European climates, the labors of February favored warming up by the fire, or chopping wood.
In the middle distance a watch tower with people inside it looks over the fields and across the river, a river with several small boats. Beyond the tower, on a hillside another worker appears to be staking more vines. Beyond him, a fifth man is blowing a hillside with what the Morgan Library describes as a team of oxen (which would be the expected livestock) but which looks very equine to me.
The landscape, which like the other calendar images in the DaCosta hours is surrounded by an ornamental frame, features a river flanked by deep hills, one of which has a castle or monastery or chapel surmounting it. The landscape looks realistic, though I can’t find any source identifying it.
