1. Please note that the National Library of South Africa in Cape Town is different from the University of Cape Town’s library which tragically burned down in a wildfire in April 2021.
2. By the time MS G.4.c.14 arrived in Cape Town in 1862, it was missing three folios (1, 10, and 102). The absence of these folios was noted by Grey’s librarian, Wilhelm Bleek, in his initial catalogue of Grey’s South African collection. See Wilhelm H. I. Bleek, The Library of his Excellency Sir George Grey, K.C.B., Presented by him to the South African Public Library: Manuscripts and Incunables, vol. 3, part 1 (London: Trübner, 1862), 4. The folios in the codex have been renumbered. The initial folio numbers, which are at the top centre of each recto, have been rewritten at the top right of each page, copying the style of the medieval Arabic numbers, then crossing the rewritten old folio number out and replacing it with a new number, written in a more modern font, also in the top right of each page, that reflected the absence of the missing folios. This means that MS G.4.c.14 has three different sets of folio numbers, a formula for considerable confusion. Indeed, there is slippage between the sets of folio numbers in the newest catalogue of the Grey Collection. See Carol Steyn, The Medieval and Renaissance Manuscripts of the Grey Collection of the National Library of South Africa, Cape Town. 2 vol. (Salzburg: Institut für Anglistik und Amerikanistik, 2002), 2:105–9. For the purposes of this article, all folio numbers refer to the original pagination, found in the top centre margin of each recto.
