- 'De Situ Albanie' - a geographical tract. A reference to Andrew, bishop of Caithness, suggests that it was originally composed in the late 12th century - the bishop having died in 1184.
- 'Cronica de origine antiquorum Pictorum' - A confused, rambling, treatise purporting to explain the origins of the Picts (and, indeed, the Scots), which is mainly recycled from the work of Isidore of Seville (d.636).
- A list of Kings of the Picts - beginning with the, supposed, founding father of the nation, and continuing until the Scots, in the person of Kenneth mac Alpin, gained control in the 9th Century. There are a few exceptions (including Cruithne, in Irish, the eponymous founder), but kings' names appear to have retained their Pictish forms.
- The, so called, 'Scottish Chronicle' (known previously, and sometimes still referred to, as the 'Pictish Chronicle') - a list of kings of the combined kingdom of Picts and Scots (Alba), accompanied by a brief chronicle of their rule, beginning with Kenneth mac Alpin and ending with Kenneth II (971-995). A blank, left for the later insertion of Kenneth's reign-length, would seem to suggest that the 'Chronicle' was originally compiled during his reign.
- A list of Scottish kings - beginning with Fergus, son of Erc, of Dál Riata, and continuing up to King William of Scotland, whose entry has a blank for his reign-length. This leads into:
- Genealogy of King William - ruled 1165-1214. William is remembered as William 'the Lion' (apparently because he chose to use a lion rampant as his coat of arms), however, the 'Poppleton Manuscript', in both his genealogy and 'De Situ Albanie', calls him William Rufus.
- A version of the St.Andrews foundation legend.
The 'Poppleton Manuscript' is a 14th century codex (Paris, Bibl. Nat., Ms Latin 4126) named from one Robert of Poppleton, on whose orders it (or a large part of it at least) was compiled at York. The codex contains several texts relating to early Scotland - all of which are in Poppleton's compilation.
