Zósimo de Panópolis (sécs. III-IV d.C.) foi um sacerdote-artesão egípcio cuja obra teve imensa importância para a alquimia antiga. Escrevendo em grego durante um período em que o Egito romanizado passava por uma queda de prestígio e incentivo das atividades nos templos, Zósimo discorre sobre práticas metalúrgicas lançando mão de todo um cabedal religioso e teórico, por vezes em simples receitas, por vezes em tratados e cartas (dirigidas principalmente a certa Teosebeia). O famoso Sobre a letra ômega, por exemplo, possui forte caráter sincrético; por meio dessa obra, Zósimo aponta diversos paralelos entre as tradições grega, egípcia e hebraica, reforçando a necessidade de uma abordagem espiritual à arte metalúrgica. Examino neste artigo alguns pontos principais de seus escritos a fim de apresentar Zósimo ao público interessado.

“…The only mixture seen to affect the colour of the gilding was RASAa. This mixture was composed of one part of NH 4 Cl, one part of (CH 3 COO) 2 Cu and a few millilitres of clear water 9. The resulting preparation was a thick green homogeneous paste with a pH of 3·5.…”

A few decades ago, heritage scientists and art historians started to study the ancient surface colouring techniques of metal art pieces. Colouring of copper and silver has already been broadly studied but no works on gold have been reported yet. This knowledge can be very important for art and technology history, conservation-restoration and surface sciences. This paper contributes to the investigation of the oldest recipe known so far to colour fire gildings. The chosen model samples, the mixture and the application of the recipe have been summarised by referring to the ancient writings known as the Arab and Syrian Alchemist Collection of M. Berthelot. The main aim of this research is to study the colour change obtained by applying the above mentioned recipe, and to identify the processes involved during this colour change. Digital imaging and scanning electron microscopy in combination with colorimetric measurements and elemental analysis have been performed to characterise the colour change and to identify its origins.

“…The fame that the Book of Secrets enjoyed in the Latin world is testified by the existence of several Latin copies which were studied and partially edited and translated into German by Ruska. 16 As anticipated, the truly exceptional character of this alchemical treatise in the context of the contemporary Arabic alchemical production lies in its clear structure, its thoroughness, and the plain language and style in which ingredients, apparatus, and operations are dealt with. In consideration of these features, the Book of Secrets attracted praise among early 20 th century historians of chemistry, and al-Rāzī became an ante litteram hero of the scientific approach to the natural world.…”

This contribution focuses on two Arabic alchemical treatises that circulated under the name of the 10th century philosopher, physician, and alchemist Muḥammad ibn Zakarīya al-Rāzī: the genuine Book of Secrets (Kitāb al-Asrār) and the spurious Book on Alums and Salts. The two treatises are discussed in the context of al-Rāzī’s genuine and spurious production and of their reception among Western scholars. By examining the contents and structural features of these two treatises, this work seeks to shed light on the relationship between perceived authority, structure, and laboratory practice in medieval alchemy.
