This is a lovely but also fairly traditional book of hours calendar image for August from The Morgan Library’s MS M.399, fol. 9v The Da Costa Hours, showing the customary labor of August, threshing grain, as well as the last reaping of grain. In the front on the left, a woman is finding the cut wheat into sheaves for drying. Front and center a double-flail wielding man is beating the ripened grains from the stocks. To his right another man with a sickle is reaping the ripe grain. In the middle distance on the left a cart drawn by two horses (one with a rider) is hauling away a load of sheaves of grain, perhaps destined for a threshing barn. In the distance beyond the cart is what looks like a man reaping on the side of a hill.
In the foreground, where the one men is threshing and his neighbor is wielding a sickle, the standing wheat and the bundles on the ground both have small brightly colored flowers of some sort. I can’t help but wonder is some of them are Cornflowers, Centaurea cyanus (Bachelor buttons in North America). Cornflowers take their name from their European habitat; they tended to grow in fields of grain, or “corn” in British English, including wheat, rye and oats. Cornflower blossoms are most commonly blue in color, but purple and pink blossoms are also possible. Other possible candidates for the flowers include the Corn Poppy (Papaver rhoeas), Corncockle (Agrostemma Githago). These meadow and field flowers are often featured in the borders of books of hours, particularly those from Flemish workshops.
