Arthur Dale Trendall, AC, CMG (28 March 1909 – 13 November 1995) was a New Zealand art historian and classical archaeologist whose work on identifying the work of individual artists on Greek ceramic vessels at Apulia and other sites earned him international prizes and a papal knighthood.
[2] In January 1940, with the encouragement of the Australian Army, Trendall, together with some colleagues at the University of Sydney, began to study Japanese codes.
As a result it was agreed that Room's group, with the agreement of the University of Sydney, would move in August 1941 to work under Nave at the Special Intelligence Bureau in Melbourne.
[5] Moreover, he was responsible for "superbly acute and well- informed observations on the subject-matter and interpretation of the vases, whether mythological, cultic, funerary, social, theatrical or artistic.
[6] On 20 July 1961 he was appointed Cavaliere Ufficiale Ordine al Merito della Repubblica Italiana.
