Discovery News writer Rosella Lorenzi has posted an exciting article about the two portraits shown above. According to Hildegard Hammerschmidt-Hummel, a professor of English at Mainz University, Germany, the one on the left shows Shakespeare as he was experiencing his first successes on the London stage, around 1594. The one on the right depicts him around the age of 50, relaxing at home in Stratford. These two newly authenticated discoveries increase the number of known likenesses of the Bard to six.
