Masterpiece of the week

A Boy and a Girl with a Cat and an Eel, 1635, by Judith Leyster — Photograph: Picture Art Collection/Alamy

A Boy and Girl With a Cat and an Eel, c1635, by Judith Leyster
In this fresh and witty portrait, the most celebrated female artist of the Dutch golden age captures the raw vitality of two anything but idealised children. The boy seems the older of the two and enormously pleased with his cat and eel. He holds the cat tight as it sticks out its claws. Is he about to feed it the eel? Leyster trained under Frans Hals and this boy has the bluff confidence of Hals’s Laughing Cavalier. Yet it’s the girl – his sister? – who looks out of the picture, wiser than her years, and makes eye contact with us in a gentle smile at his boyish pride.
• National Gallery, London.

Gateway by Joana Vasconcelos
Gateway is an art installation swimming pool in a landscaped formal garden and accompanied by a glass-dome space. The artwork, part of the Edinburgh art festival, is made from more than 11,500 hand-painted and glazed tiles traditionally manufactured in Vasconcelos’s native Portugal. The public will be able to book sessions to swim there. See more work from this year’s Edinburgh art festival in our gallery.
