The exhibition “And there’s the Humor of it: Shakespeare and the Four Humors,” will be on view from April 9 through May 19 in the Bookers’ display area in Mantor Library, 116 South St., in Farmington. An opening reception is set for 2:30-3:30 p.m. Sunday, April 8.

Sponsored by the National Institute of Health, the display illuminates the four bodily humors — blood, yellow bile, black bile and phlegm — which were understood by Shakespeare, and everyone in his world, to define people’s physical and mental health, and their personality. The NIH exhibition will explain the language of the four humors and their influence in Shakespeare’s plays. The exhibition was developed and produced by the National Library of Medicine, National Institutes of Health and the Folger Shakespeare Library.

To enlarge on the infinite variety of the Shakespeare theme, the Shiretown Bookers’ accompanying exhibition, “Universal Like the Sun: a Shakespearean Ragbag”, will feature members’ books and illustrations on a fascinating range of topics, from the Bard’s biography, geographical setting and academic reputation, to staging, set design, costuming and great performances.
