left a frank comment on Burchard's character at the beginning of his private ceremonial Diary:<ref>J.J.J. von Döllinger, "Das Pontificat Julius' II.," in: Beiträge zur politischen, kirchlichen, und Cultur-Geschichte III. Band. (Wien 1882), p. 364. Licet autem novus et inexpertus sim tanquam asinus ad liram, conabor sic per crebras actiones et per annales actiones evadere, ut officio meo satisfaciam. Sic quaeso, uti in hoc principio, dum gesta tantorum patrum exequar et describam, non irrideant mea scripta maligni detractores, praesertim ille meus collega Johannes Burchardus, multo magis socius in officio quam amicus meus in charitate, quae nulla est in eo. Nam cum me intellexit ad officum aspirasse, illico omnes conatus in me, quos potuit et quos scivit ac plus quam potuit et scivit, exasperavit, ut me ejiceret.</ref> Granted however new and untried I may be, like an ass at the lyre, I shall try to do my duty satisfactorily through frequent efforts and entries year by year. And so I ask that at this beginning as I am recording and explaining the actions of so many prelates, ill-wishing detractors not laugh at my writings, especially my colleague Johannes Burchard, who is much more of an associate in my office than my friend in charity, of which there is none in him. For when he realized that I aspired to his job, from that point he tried everything against me that he had the power and the knowledge to do, and more, and strove to get me dismissed. The Liber Notarum is still maintained by the papal Ceremoniere. Though he only described musical details when in the context of innovations or mishaps, his account is an important source for details of papal choir singing. Among other details, he noted the use of polyphony in settings of the Passion, a practice apparently introduced from Spain, and the performance of the now-lost motet Gaude Roma vetus, written in honor of Pope Alexander VI to a text by Johannes Tinctoris. Burchard's residence, built in 1491, survives and can be seen at Via del Sudario 44, in Rome. Burchard was also known as "Argentinus" from the Latin name for Strasbourg, and the tower on his palace gave the name "Torre Argentina" to the district, still retained in the Largo di Torre Argentina and other names. In popular culture Johann Burchard was portrayed by Ralph Nossek in the 1981 BBC-RAI production TV series The Borgias, by Simon McBurney
