This is also known as the Florencia, or Florence Codex. It contains roughly the first 100 Cantigas; the E Codex contains all of the Cantigas, and the standard numbering scheme is derived from it. While the authors of the Cantigas are unknown, it is believed that King Alfonso himself authored some of them, as he refers to himself in the first person. Gallego-portugu'es, the language of the Cantigas, was a poetic language also cultivated by trovadores whose maternal language was another one.
