title="Alchemist">alchemist</a> during the first half of the fifteenth century. </p><p>Little is known about Johann's life, but his name probably indicates that he came from <a href="/wiki/Ledce_(Brno-Country_District)" title="Ledce (Brno-Country District)">Ledce u Židlochovic</a> (German Laatz). </p><p>His <i>Tractatus aureus de lapide philosophorum</i> (The Golden Treatise on the <a href="/wiki/Philosopher%27s_Stone" class="mw-redirect" title="Philosopher's Stone">Philosopher's Stone</a>) was first printed in 1611 and was later reprinted in <a

Chemicum">Theatrum Chemicum</a></i>. In that text, he presents a transmutation of metals from quicksilver, sulfur, and gold. Laz also claims to be a student of the alchemist Anthony of Florence (Antonius de Florentia), who was supposed to have been murdered in Bohemia. </p><p>Benedikt Nikolaus Petraeus cites Johann of Laz in the foreword to his edition of <a href="/wiki/Basil_Valentine" title="Basil Valentine">Basil Valentine's</a> <i>Chymischen Schriften</i> (1667). In that text, he discusses the supposed alchemical activity of <a href="/wiki/Barbara_von_Cilli" class="mw-redirect" title="Barbara von Cilli">Barbara von Cilli</a>, widow of the Holy Roman Emperor <a href="/w/index.php?title=Sigismund,_Holy_Roman_Emperor)&action=edit&redlink=1" class="new" title="Sigismund, Holy Roman Emperor) (page does not exist)">Sigismund of Luxembourg</a>.
