Marcus Aemilius Lepidus was a Roman consul for the year 158 BC, together with Gaius Popillius Laenas. He was a praetor in year 161 or earlier, and was possibly the presiding praetor when the Roman Senate was holding discussions on the dispute between Magnesia and Priene.* T.R.S. Broughton, The Magistrates of the Roman Republic (American Philological Association, 1951, 1986), vol. 1, pp. 443 and 444 (note 2), and vol. 2, p. 526. He is mentioned in a context that suggests he was one of the Decemviri sacris faciundis, a priestly college (collegium) who oversaw the Sibylline Books in year 143.Broughton, MRR1, p. 473.
