Tro y Ortolano gave him permission to publish the codex in a reproduction, and Brasseur de Bourbourg gave it the name "Troano Codex" in his honour. His identification of the codex was significant, as it was the only third such Maya codex to have been uncovered (the second, the Codex Paris, had been discovered by the French scholar Léon de Rosny only a few years before). In particular, Brasseur de Bourbourg recognised its exceeding rarity, since de Landa's "Relación", which he had earlier rediscovered, gave an account of how he had ordered the destruction of all such Maya codices he could find, and many volumes had been burned.
