There are no examples of the Western Lombard language from that age, but some pieces were written in related Gallo-Italic languages, such as Sordello da Goito's  Sirventese lombardesco (in the Eastern Lombard language of Mantua), as well as Rayna possentissima (1254), lauda of the Servi della Vergine, and the notary registers of Bologna (in whose white spaces, folk tales or literary poems were inserted to avoid illegal insertions), all of which are in the Bolognese.
The lack of examples from that era means there is no documentation of the Western Lombard language, but some pieces were written in related Gallo-Italic languages, such as Sordello da Goito's Sirventese lombardesco (in the Eastern Lombard language of Mantua), along with Rayna possentissima (1254), lauda of the Servi della Vergine, and the notary registers of Bologna (where folk tales or literary poems were inserted into blank spaces to avoid unauthorized insertions), all of which are in the Bolognese dialect.
