Finding Ophelia.

Shakespeare Birthplace Trust's Finding Shakespeare blog looks at various depictions of Ophelia, focusing initially on a 1789 painting by Benjamin West:

"The flowers in this painting do not necessarily depict the individual emotions such as remembrance and thoughts that they do in Shakespeare’s text, but instead we see a collection of wild flowers in Ophelia’s hair, in her clothes and on the floor. They symbolise other-worldliness and link her with nature and perhaps also mythology. They emphasise Ophelia’s incongruity with court and the characters around her."

There's also an excellent video of Anna Griffith revealing key items from their collection.
