Bridget Riley at the Hayward Gallery

London's Tate Modern is home to some gorgeous Bridget Riley canvases, huge rectangles of rhombic mosaics, in shifting colour that one can stand in front of and lose oneself in. A fifteen minute stroll west along the embankment, the Hayward Gallery seems to have all of them and then carpet bombs the place with a massive selection of the artist's extraordinary, life-long output. The gallery's airy spaces are filled with a veritable cornucopia of her work, spanning from 1947 to today.

Charles I, King and Collector

No better insight can be gained into the character of King Charles I - the king who in 1629 dissolved Parliament to begin an eleven-year stint of Personal Rule - than by visiting The Royal Academy of Arts' exhibition entitled "Charles I, King and Collector". His art collection was at the time the largest in Europe. Tranches of it were inherited; much of it was commissioned or purchased from the public purse. Paintings, sculptures, tapestries, manuscripts and miniatures totalling the best part of two thousand in number decorated the royal palaces.

Flowers in a glass vase

Flowers in a glass vase by the Dutch painter Jacob van Walscapelle is only midway in size between A1 and A2 paper sizes, an oil painting dwarfed by many of the larger canvases around it at the V&A Museum in London. What it lacks in scale it makes up for in quality. It is as if the light-infused oil paint applied just after the middle of the 17th century is still blazing off its canvas some 350 years later.
