Literary style: De Vere's known writings exhibit a striking similarity in style, vocabulary, and imagery to Shakespeare's works. Scholars have identified numerous parallel passages and verbal echoes, suggesting a shared authorship.
Education and background: De Vere received an excellent education and was exposed to the literary and theatrical world from a young age. He was known for his poetic talent and was a patron of the arts. This background aligns well with the knowledge and sophistication evident in Shakespeare's plays.
Social connections: De Vere moved in the same circles as many prominent Elizabethan figures, including members of the royal court and the literary community. This would have provided him with the necessary access to the ideas, events, and people that influenced Shakespeare's writing.
Historical allusions: Many of Shakespeare's plays contain specific historical references and allusions that match events in De Vere's life or within his circle of associates. This suggests a personal connection to the material and a firsthand knowledge of these historical events.
Contemporary accounts: There are several contemporary references and hints that link De Vere to Shakespeare's works. For example, Francis Meres, a literary scholar of the time, praised De Vere as "the best for comedy amongst us" and mentioned his "vein most excellent" in tragedy.
Autobiographical elements: Some of Shakespeare's sonnets and plays are believed to contain autobiographical elements that align with De Vere's life and experiences. Scholars have found parallels between events in De Vere's life and the themes and events depicted in Shakespeare's works.
Overall, the evidence points to Edward de Vere, the 17th Earl of Oxford, as a strong contender for the true author behind the name "William Shakespeare."
