Exhibition of the week Love’s Labours Found Haunted portraits to spook the imagination - or, as the gallery has it, important new discoveries in Elizabethan and Jacobean portraiture. As commercial galleries open before museums, this is your best bet for a historical show this month. Philip Mould and Co, London from 21 April until 29 May Also showing Mat Collishaw An ambitious permanent film installation by this intelligent and thoughtful artist, projecting a digitally created image of a lost Saxon church that weaves together histories of Englishness and photography. Riverside Walk, near All Saints Church, Kingston, Surrey. Idris Khan New paintings inspired by Vivaldi’s music and the mystery of colour. Victoria Miro Gallery, London until 15 May. Damien Hirst Takeover The original Young British Artist may not be that young now but he is certainly productive, and has undertaken to fill Gagosian’s space near King’s Cross for a year. Gagosian Britannia Street, London through 2021. Rachel Eulena Williams Bright and dynamic, explosive abstractions that exist somewhere between painting and sculpture. Modern Institute, Glasgow ongoing. Image of the week American artist Stacey Lee Webber has embroidered money for more than a decade. She started as a way to question the value of work by meticulously stitching patterns on to worthless dollar bills. The latest incarnation – the Insurrection Bills – is a response to the US’s febrile political climate. See more images here.

Fascinatingly and mysteriously, her male contemporaries also painted and sculpted strong images of women. Here the intense Catholic artist Guercino portrays one of the Sibyls, female prophets from ancient Rome who were reimagined as harbingers of Christianity, as a characterful enthroned presence. She is very real and human as she turns to chat to the putto – also a classical myth Christianised into an angel. Guercino’s monumental, static scene is brought to life by his deep and moving sense of colour.
