<p><em>The Mirror of Alchimy</em> is a short alchemical manual known in Latin as <em>Speculum Alchemiae</em>. Translated in 1597 it was only the second alchemical text printed in the English language. Long ascribed to Roger Bacon (1214-1294) the work is more likely the product of an anonymous author who wrote between the thirteenth and the fifteenth centuries.</p>
