From a Book of Hours that was produced (between 1496 and 1506) for Joanna of Castile, the daughter of King Ferdinand of Aragon and Isabella of Castile. The British Library: “The strenuous work of summer continues in these two miniatures from the calendar for July, which focuses on the yearly harvest of wheat.  On the left folio four men are at work in a field, in what must be very warm weather; the men have all rolled up their sleeves, and two seem to have divested themselves of their trousers as well.  On the right, beneath a small and rather scowly lion (for the zodiac sign Leo) another group of men are bringing their harvest to a timbered barn.”
