Meaning

Oratorium and Laboratorium name the paired settings of the final practical exhortation. In the oratory the philosopher asks for illumination and right understanding; in the laboratory he must handle Magnesia rightly in a physico-chymical way. The source's marginal headings, rather than a modern reconstruction of a building, establish the pair.

Use in the book

The sentence begins on p. 173 after the claim that the due subject provides a sure ground. This possession does not end the need for guidance. The Father of Lights must be invoked in spirit and truth to give inspired wisdom, insight in the mirror of the mind or otherwise, and admonition while reading philosophical books. The continuation on p. 174 makes the desired result specific: recognize where the truth about preparation has been written, receive good promptings from the Good Spirit, and govern the handling of the matter rightly.

The two settings are therefore connected by one petition. Prayer is directed towards the practical problem of preparation; labour is to be conducted under the guidance requested in prayer. The margin's “theoretically and practically” reinforces this conjunction. Neither a self-sufficient laboratory technique nor prayer without treatment of the proper subject is the programme described.

The term laboratory also has a larger occurrence at pp. 62–632. The whole wide World is God's universal laboratory, where Nature continually prepares the natural subject without the Artist's useful hand. The practitioner's laboratory does not replace that prior work. It begins with what has already been furnished and asks for the right way to continue. This distinction helps explain why taking a false subject cannot be cured merely by increasing labour or devotion.

The pair is sometimes imagined as a symmetrical visual arrangement. This treatise supplies a more modest and more exact material fact: the headings stand on consecutive pages of one running argument. They are to be read through a page turn, with the prayer passing into its practical object.

Translation in this edition

Translate the settings as “oratory” and “laboratory,” keeping the Latin headings available. These pages do not describe room dimensions, equipment or an architectural plan. The modern note correctly observes that pp. 173–1742 occupy the two sides of one leaf, not facing pages. The damaged end of the laboratory gloss should not be completed conjecturally.

Source note

The p. 174 laboratory gloss becomes illegible after a word beginning Muric-. The edition marks the loss; no missing authority or maxim should be reconstructed from the fragment. James 1:5 in the p. 173 margin and 2 Timothy 2:7 in the p. 174 margin support the two parts of the petition for wisdom and understanding.
