There were female pioneers of photography before Christina Broom, most notably Julia Margaret Cameron. And others have hidden their light under a bigger bushel: Vivian Meier's body of work remained stashed away only to be discovered after her death. Broom's importance is partly one of timing: she prowled the streets of London at a time of great historical significance. As suggested by Soldiers and Suffragettes, the title of a new exhibition and book celebrating her work, she was a witness to the struggle for universal suffrage and the First World War.

It’s far too easy to think about the history of art as a series of class acts, with one superlative achievement following another. Exhibitions tend to encourage this view, and the notion of a superstar artist is key to persuading us that the latest blockbuster is unmissable.

The Iranian-born New York resident painter YZ Kami, now in his mid-fifties, continually plays with our hunger to look at “reality” while being seduced by abstraction and repetition. In 17 canvases, painted over the past two years, Kami explores two distinct and recognisable styles or idioms that however much in common they have with contemporary concerns he has made his own. The results are both powerful and pleasurable. 

One masterpiece and two superb portraits both dominate and sum up in vivid fashion the complex personality, long life and astonishing trajectory of the first Duke of Wellington

The grand but domestic setting of Hertford House, home of the Wallace Collection, makes a fitting backdrop to an exhibition of paintings by Joshua Reynolds. The Marquesses of Hertford acquired some 25 paintings by Reynolds in the artist's lifetime, and after it, and the 12 that remain in the collection form the focus of this exhibition.

Oh, Dr Pozzi! This gorgeous man is garbed in a red wool, full-length robe, almost completely obscuring his elegantly gleaming white shirt. The shirt collar frames his face, casting light, and its frilled cuffs emphasise his improbably long-fingered hands in a lively gesture.

It seems only right that Sir Anthony Van Dyck’s last Self-portrait, 1640-1 (pictured below right), saved for the nation last year as a result of a very public campaign, should now embark on a tour of the country as much in recognition of the 10,000 or so individuals who contributed to its purchase fund, as of its significance to British portraiture.

It is hard to know whether the thematic and stylistic threads running through this year’s Taylor Wessing Prize are evidence of some general shift in approach, or simply reflect the judges’ tastes. In any case, where last year’s shortlist featured stark portraits highlighting the tricky power relationships between photographer and subject, this year’s competition tends towards something gentler and more empathetic – an altogether homelier sort of photography.

Written in the 16^th century, Giorgio Vasari’s Lives of the Artists continues to underpin our understanding of the Renaissance, and its author is blamed, often with some justification, for a multitude of art historical anomalies. But there can be little doubt that Vasari’s omission of Giovanni Battista Moroni, a fine painter of portraits and religious subjects, has been instrumental in the disappearance of this artist from the Renaissance halls of fame.

The chatty, loquacious, exuberant Simon Schama, whose seminal 1987 book on Holland in the 17^th century, The Embarrassment of Riches, transformed the anglophone’s understanding of the Dutch Republic, describes himself as historian, writer, art critic, cook, BBC presenter. He is also the University Professor of History and Art History at Columbia, and has written 14 substantial and even significant books. On several of his subjects, from British art, slavery in America and landscape in culture to the history of the Jews, he has presented popular television series.
