De Situ Albanie (or dSA for short) is the name given to the first of seven Scottish documents found in the so-called Poppleton Manuscript, now in the Bibliothèque nationale de France, Paris. It was probably written sometime between 1202 and 1214, in the reign of the William the Lion, by a French-speaking[dubious – discuss] resident of Scotland (north of the Forth), as an introduction to the compilation.
The title is taken from the opening words of the piece, which reads:
"De Situ Albanie que in se figuram hominis habet quomodo fuit primitus is septem regionibus diuisa quibusque nominibus antiquitus sit uocata et a quibus inhabitata"
