"Lucius Aelius Caesar (January 13, 101 – January 1, 138) was the father of Emperor Lucius Verus. In 136, he was adopted by Hadrian and named heir to the throne. He died before Hadrian and thus never became emperor. After Lucius´ death, he was replaced by Antoninus Pius, who succeeded Hadrian the same year." - (en.wikipedia.org 15.03.2020)
