On 1 January 145, Marcus was made consul a second time. Fronto urged him in a letter to have plenty of sleep 'so that you may come into the Senate with a good colour and read your speech with a strong voice'. Marcus had complained of an illness in an earlier letter: 'As far as my strength is concerned, I am beginning to get it back; and there is no trace of the pain in my chest. But that ulcer [...] I am having treatment and taking care not to do anything that interferes with it'. Never particularly healthy or strong, Marcus was praised by Cassius Dio, writing of his later years, for behaving dutifully in spite of his various illnesses. In April 145, Marcus married Faustina, legally his sister, as had been planned since 138. Little is specifically known of the ceremony, but the biographer calls it 'noteworthy'. Coins were issued with the heads of the couple, and Antoninus, as "Pontifex Maximus", would have officiated. Marcus makes no apparent reference to the marriage in his surviving letters, and only sparing references to Faustina.
