Exhibition of the week Beyond Form: Lines of Abstraction, 1950-1970 Abstract art by women including Eva Hesse and Marisa Merz, from the era between 1950 and 1970 when modernism triumphed, then broke into more organic and personal visions. Turner Contemporary, Margate, from 3 February until 6 May Also showing Paolozzi at 100 A celebration of one of the first pop artists who progressed from small collages to sculptures in heavy metal. Was he a modern great or a bit clunking and pretentious? Modern (Modern Two), Edinburgh, until 21 April Entangled Pasts, 1768–now: Art, Colonialism and Change The radical Georgian artist William Blake loathed the Royal Academy, which had then been recently founded, as an establishment club. Here it confesses its own sins, castigating itself for its connections with slavery. So Blake has the last laugh. Royal Academy, London from 3 February until 28 April John Russell: Foyer An installation that involves angels, flies and a portal to hell in the gallery floor. Arcadia Missa, London, until 17 February Alexis Hunter A survey of this feminist artist who died in 2014 leaving a striking body of radical art.

What’s going on here? Is this painting a cynical act of cultural appropriation, an arrogant imperial theft of others’ garb? The truth is more complex. Robert Shirley was ambassador to Abbas I of Persia, known as Abbas the Great, under whose rule Iranian culture reached brilliant heights. Shirley was besotted, and adopted the dress of his hosts. He and his wife, Teresia Shirley, who was Circassian, were in Rome, in their habitual finery, when Van Dyck met and painted them. He lavishes Titianesque, fantastical brushwork on Shirley’s robes while depicting his face with precise realism.
