Carta de Logu in the context of "Incunabulum"

Eleonora's falcon (Falco eleonorae) is a medium-sized falcon. It belongs to the hobby group, a rather close-knit number of similar falcons often considered a subgenus Hypotriorchis. The sooty falcon is sometimes considered its closest relative, but while they certainly belong to the same lineage, they do not seem to be close sister species. The English name and the species name eleonorae commemorate Eleanor of Arborea, Queen or Lady-Judge (Juighissa) and national heroine of Sardinia, who in 1392, under the jurisdiction conferred by the Carta de Logu, became the first ruler in history to grant protection to hawk and falcon nests against illegal hunters. The genus name Falco is from Late Latin falx, falcis, a sickle, referring to the claws of the bird.

Eleanor of Arborea or Eleanor De Serra Bas (Sardinian: Elianora de Arbarée / Elianora De Serra Bas, Italian: Eleonora d'Arborea / Eleonora De Serra Bas; 1347 – June 1404) was one of the most powerful and important, and one of the last, judges of the Judicate of Arborea in Sardinia, and Sardinia's most famous heroine. She is also known for updating of the Carta de Logu, promulgated by her father Marianus IV and revisited by her brother Hugh III.
