[3] Holland's affinity with the art of the past is reflected in the genres and themes to which he habitually returns, namely the nude, still life and mythology.
The development of his realist style was much influenced by early study and copying of old masters, in particular the work of Titian and Velazquez.
There are implications – whether of a mystery, or dark secret hidden in the protagonists’ past – which the viewer only manages to perceive as the slightest of signs, an impression, or as a subtle but discomfiting metaphor.
[8] Goya's Los Caprichos were the original inspiration for Holland's figures-in-the-sky paintings, specifically Witches in Flight, 1797–98.
[9] Holland's interest in portraying athleticism led to his painting practitioners of Cardiff's No Fit State circus, capturing key moments showing the physical strength, poise and coordination of the company's trapeze artists, acrobats and aerialists.
[10] During the COVID-19 pandemic, Holland created portraits of key workers, in recognition of the vital role of the National Health Service.
[11] A series of these paintings of essential workers, made during lockdown, formed part of Holland's 80th birthday exhibition which opened at the Martin Tinney Gallery on 16 September 2021.
