• The largest survey of the work of visionary artist and poet William Blake to be seen in the UK in a generation has opened at the Tate Britain in Millbank. William Blake features more than 300 works with highlights including The Spiritual Form of Nelson Guiding Leviathan (c1805-9) and The Spiritual Form of Pitt Guiding Behemoth (c1805) which, in a bid to see them as Blake intended, have been digitally enlarged and projected onto the gallery’s wall, providing them with the sort of the scale he had envisaged for them but never realised. The actual works themselves are displayed nearby in a recreation of the artist’s only significant attempt to acquire a public reputation as a painter – his ill-fated exhibition of 1809 which took place in a room over his family’s hosiery shop. The exhibition also provides a focus on London, described as a “constant inspiration” for Blake, and highlights the vital role of his wife Catherine played in the creation of his engravings and illuminated books with illustrations to Pilgrim’s Progress (1824-27) and a copy of the book The complaint, and the consolation Night Thoughts (1797) on display, both of which are thought to have been coloured by Catherine. Other highlights include what is thought to be the only self-portrait of Blake – exhibited in the UK for the first time, the work Albion Rose (c1793) depicting the mythical founding of Britain, illuminated books such as Songs of Innocence and of Experience (1794) and some of his best-known paintings including Newton (1795-c1805 – pictured above) and Ghost of a Flea (c1819-20). The exhibition closes with The Ancient of Days (1827), a frontispiece for an edition of Europe: A Prophecy, which was completed only days before Blake’s death. Runs until 2nd February. Admission charge applies. For more, see www.tate.org.uk. PICTURE: William Blake (1757-1827) Newton 1795-c1805 (Colour print, ink and watercolour on paper, 460 x 600mm Tate).

• A new gallery exploring how London’s scientists and artisans transformed our understanding of the world over 250 years spanning the period from the mid-16th century to the end of the 18th century opens at the Science Museum in South Kensington today. The 650 square metre gallery, known as ‘Science City 1550-1800: The Linbury Gallery’, features iconic objects such as Sir Isaac Newton’s famous work, Principia Mathematica, Robert Hooke’s microscope (pictured), and objects including an air pump and ‘Philosophical Table’ which were commissioned by King George III as the king conducted his own scientific investigations. There’s also a range of machine models including one of a pile driving machine used in the construction of Westminster Bridge in the 1740s. The gallery is free to visit.
