"Annie Laurie" is an old Scottish song based on a poem said to have been written by William Douglas (1682?–1748) of Dumfriesshire, about his romance with Annie Laurie (1682–1764). The words were modified and the tune was added by Alicia Scott in 1834/5. The song is also known as "Maxwelton Braes".
The title of this example of art is Sarcophagus of the church of Santa Maria Antiqua.
It does contain Christian symbolism that was unrecognizable by pagans. It was also possibly made to be the tomb of a rich Christian living in the third century. It was made in 275 CE and contains the representations of many Biblical and non-biblical people.
