The transcription provided here is based on the exemplar from the State archive in Udine, cited in Sources field and displayed in the Image field. However, Bianchi's edition is based on another manuscript, one kept in the Archive of the Chapter of Udine. A critical edition of Thesauri claritas that will compare both manuscripts is definitely a historiographical desideratum, one that will, at least for entries concerning Istria, be undertaken in the near future. Both manuscripts are based on the late 14th century original, but both are copies made in the first decades of the 15th century.
