Tiberius Gemellus, son of Drusus Julius Caesar and Claudia Livia Julia, adopted son of Caligula, and grandson of Emperor Tiberius and Drusus the Elder, was born on October 10th, 19 A.D. Because I was curious, I looked it up, and it was a Tuesday. His birthday stood out because I have been reading a lot of Greek mythology, and novels based on the story of Achilles in the Trojan War. I know the birth year of Tiberius Gemellus was quite far away from antiquity, but I will recommend two of the novels nonetheless: The Song of Achilles by Madeline Miller and The Silence of the Girls by Pat Barker.
