His lectures, published posthumously, were described by art historian Benedict Read as "the most consistent and intelligent exposition of sculptural thinking" of his era.
[2][1] Despite the considerable success he enjoyed during his lifetime, his reputation was not long-lasting, and the rise of the New Sculpture shortly after his death led to his works being neglected.
"[13] Apart from the 1838 bust of Queen Victoria, his first major works were statues of Thomas Cranmer, Hugh Latimer and Nicholas Ridley for George Gilbert Scott's Martyrs' Memorial in Oxford, which he completed under Chantrey's direction in 1841.
[1] Originally strongly influenced by Chantrey, Weekes developed a more individual style towards the end of the 1840s, introducing naturalistic detailing into his neo-classical works.
"[2] Weekes was, however, against what he considered excessive realism, as exemplified by his contemporary Carlo Marochetti; he always opposed the colouring of sculpture, instead applying, for example, deep undercutting.
It depicts the couple kneeling in a pose that echoes Chantrey's monument of 1835 to Reginald Heber in St Paul's Cathedral, except that Lady Elizabeth leans against her husband's shoulder with evident affection.
Weekes, however, depicts not a heroic nude in the neo-classical tradition but a bloodless corpse, and realistic details, including seaweed wrapped around his arm, recall the particulars of Shelley's death by drowning in Italy.
[2][1][15] The monument was the subject of contemporary critical acclaim,[1] but St Peter's Church, Bournemouth, where Mary Shelley was buried, refused to take the work, and it was installed instead in Christchurch Priory.
[2][17] Other works in this genre include Sardanapalus (1861), from Lord Byron's verse tragedy on the Assyrian king,[18] and Luna (1866), depicting a girl with the moon as a shield.
[19] He also continued his early success with realistic historical figures, at that time very fashionable, with a series of works including John Hunter, after a portrait by Sir Joshua Reynolds, for the Royal College of Surgeons in London (1864);[1][20] William Harvey, with a heart resting in his right hand, for the University Museum of Natural History in Oxford (1864);[21] Charles II, accompanied by a spaniel, for the Palace of Westminster (1869; now in the Old Bailey);[1] and Sir Joshua Reynolds for a garden designed by James Knowles in London's Leicester Square (1874).
Although Weekes was not on Queen Victoria's original list of sculptors, being selected to work on the project only after John Gibson declined to participate, his group occupies the preferable south side of the finished monument.
A central female figure holds an hourglass, symbolising the critical nature of time to industry, while an ironworker stands at his anvil and a potter and weaver offer their wares.
