Notebook of the herald Hendrik van Heessel (first mentioned in 1433, when he acquired the right to wear a heraldic tabard from Emperor Sigismund following the emperor's Roman coronation; he died in 1470), stored in the Henrik Conscienc Library in Antwerp (Belgium), the manuscript of which is available on the Internet, František Pícha deals with the contribution of the Czech and Moravian Coats of Arms in the notebook of the herald Hendrik van Heessel published in Genealogical and Heraldic Information 2013, Brno 2014, pp. 5-18. Heraldic drawings irregularly appearing in the manuscript have a relatively high artistic quality. They must have been made occasionally when the herald wanted to record a fact that caught his attention that might be useful in the future.
The coat of arms of the Moravian margrave is drawn on folium 55v: a crowned silver-red checkered eagle with gold armor in the blue field of shield. Sixteen coats of arms of Moravian noble families accompany the Moravian eagle on the 56r-57r foils. They are marked in German as the coats of arms of the lords subject to the Duke of Albrecht of Austria as the Moravian Margrave: "Daz seyn dy lant heren dy under herzog Albrecht von osterreich margrave zu meraun etc gehoren hir nach aufgman wapenen gesnaben".
A similar collection of twenty-six coats of arms of Bohemian noble families, which bears the emblem of the Bohemian king, with a similar note about their affiliation with the Bohemian king, can be found on foils 61v-63r: Daz seyn dy lant heren ritter und knechten dy zu der wapen seyn geporen um dem only from here to the end of the coat ".
