"all Byzantine coppers and golds under a Tiepolo sky of enamelled blue"

Giovanni Battista Tiepolo (1696-1770) was, according to the National Gallery, "the greatest Italian Rococo painter... His imaginative decorative frescoes are light in colour and airy in feel."

Tiepolo's skies are particularly fine, and are revered by art lovers the world over.

An Allegory with Venus and Time, painted in the 1750s, has an interesting connection to The Sea because the Three Graces appear in the sky (Grace is the name of the upper-class family that holds the young Max in awe).   It hangs in Room 40 of the National Gallery in London.
