The Mutus Liber is an epistemological treatise. The alchemical laboratory is the mind. In it, thoughts are chemical compounds and their processes are reactions producing knowledge. The operation works on the mind. The alchemical transmutation takes place in the mind, by the mind and through the mind in all its stages, conscious, subconscious, unconscious and beyond. Therefore, the key to interpret the plates and to open the mouth of the Mute Book is gnoseological. The chemical elements, consequently, are only metaphors to describe the epistemic process.

Reprint of the original, first published in 1841.

This is a new critical edition (in two volumes) of Vossius' Latin Poeticae institutiones, with a translation in English, an introduction, annotations and a commentary. In 1647 the Amsterdam professor Gerardus Vossius published his main work on poetics, Poeticarum institutionum libri III, which can be considered as an important result of the Dutch Golden Age. In the same year two shorter works appeared, De artis poeticae natura ac constitutione, which is an introduction to the main work, and De imitatione, which elaborates on two aspects of poetics: imitation and recitation. These are added in appendices, also with a translation, but without a commentary. Now this important early modern work on the making of poetry (labeled by Sellin as 'The last of the Renaissance monsters') is made available also for readers without Latin.

This is the first edition since its original publication of Daniel Heinsius’ Latin tragedy Auriacus, sive Libertas saucia (Orange, or Liberty Wounded, 1602), with an introduction, a parallel English translation, and a commentary. Centering on the assassination of William of Orange, one of the leaders of the Dutch Revolt against King Philip II of Spain, Auriacus was Heinsius’ history drama, with which he aimed to raise Dutch drama to the level of classical drama. Highly influential, the tragedy contributed to the construction of a national identity in the Low Countries and launched Heinsius’ long career as an internationally celebrated poet and professor at Leiden University.
