This painting’s title refers to the Italian Renaissance artist Alesso Baldovinetti (about 1426-1499). Sheffield-born Tyzack recognised visual parallels between his completed work and the folds and hair details in Baldovinetti’s ‘Portrait of a Lady in Yellow’ (National Gallery, London.) Tyzack’s painting exploits the relationships between colours and the multi-directional movements of the wavy forms – he aimed to flow them across the whole canvas surface. The famous American critic Clement Greenberg chaired the jury of the 1965 John Moores exhibition, in which this work won first prize. The exhibition reflected his advocacy of ‘colour-field’ painting in which abstract artists used large, flat expanses of colour.
