“The small wisdom is like water in a glass:
clear, transparent, pure.
The great wisdom is like the water in the sea:
dark, mysterious, impenetrable.”

“Mystery: Time and Tide shall pass,
I am the Wisdom Looking-Glass.”
Part III : The Mystic Ruby
The Flower of Old Japan and Other Poems (1907), The Flower of Old Japan
Context: p>Mystery: Time and Tide shall pass,
I am the Wisdom Looking-Glass.This is the Ruby none can touch:
Many have loved it overmuch;
Its fathomless fires flutter and sigh,
Being as images of the flame
That shall make earth and heaven the same
When the fire of the end reddens the sky,
And the world consumes like a burning pall,
Till where there is nothing, there is all.</p

Go Rin No Sho (1645)
Context: Second is the Water book. With water as the basis, the spirit becomes like water. Water adopts the shape of its receptacle, it is sometimes a trickle and sometimes a wild sea. … If you master the principles of sword-fencing, when you freely beat one man, you beat any man in the world. The spirit of defeating a man is the same for ten million men. … The principle of strategy is having one thing, to know ten thousand things.

Rembrandt's 'recipe for a stopping-out varnish' on the verso of a drawing 'Landcape with a River and Trees', undated, c. 1654-55; (Benesch 1351) http://remdoc.huygens.knaw.nl/#/document/remdoc/e12886
It is evident that Rembrandt refers (alas fragmentarily) to a so-called 'stopping-out varnish', used to terminate the bite of acid in select areas of a plate that had already been exposed to the etching agent. Thus other portions will remain exposed to the acid to deepen the bite. Also Samuel van Hoogstraten, the first student of Rembrandt in Amsterdam, mentions the use of such a varnish in his 'Inleyding tot de Hooge Schoolde der Schilderkunst', Middelburg 1671 / Rotterdam 1678
1640 - 1670
