[14][d] Fifteen days after the battle Nennius died of his head wound, and was buried at London (the "City of the Trinovantes"), near the North Gate.
[23] Wace also embellished details not given by Geoffrey, adding that the name Crocea Mors was "stamped with letters of gold" on the upper part of the sword, next to the hilt.
[26] The Anglo-Norman French chronicle Scalacronica (c. 1363) by Thomas Grey also contains an account of the Julian invasion, largely derived from Wace, though the relevant text (in the Roman History section) was never published in past extracts;[27][g] the work calls the sword Crochi Amour ("Crooked Love"), though this may be a scribal error.
In the poetry collection The Mirror for Magistrates Nennius is portrayed as an "inspirational lesson for future British people to defend their country from foreign invasion".
[34] In the Parts Added to The Mirror for Magistrates, Nennius gives speech accusing Caesar of cheating by poisoning the sword-tip to deal him a shallow wound ("scarce he perced had the skin") whose venom nevertheless killed him ("my braynes it ranckle in") in fifteen days time.
[36] The artifact in question plausibly refers to the alleged sword Nennius took from Caesar, kept in the Tower of London, mentioned in the Anonymi Chronicon Godstovianum (15th cent.).
[39] Nennius also appears in plays in the Jacobean era, notably Jasper Fisher's Fuimus Troes and John Fletcher's Bonduca (c. 1613).
