Masterpiece of the week

Portrait of a Young Man, c1480-85, by Sandro Botticelli

This portrait is astonishingly immediate and fresh, like looking at someone you’ve met in the street. Botticelli captures the pensive personality of an unknown 15th-century youth with such sensitivity and precision that we almost don’t notice the artistic accomplishment – we’re so directly taken with the young man’s hesitant and searching eyes.
National Gallery, London.

Image of the week

A Basket of Roses, 1890, by Henri Fantin-Latour
This French painter’s still life was adapted by graphic artist Peter Saville in 1983 as the cover of the New Order album Power, Corruption & Lies. It hangs now at Manchester Art Gallery in the exhibition True Faith – given a five-star review by Adrian Searle – which assesses the artistic legacy of the band and its predecessor Joy Division.
Manchester Art Gallery, until 3 September.
