During his time in Egypt, Lucas developed an expertise in the analysis and preservation of objects recovered from excavated ancient Egyptian sites.[1] When in November 1922 the archaeologist Howard Carter discovered the tomb of Tutankhamun with its contents largely intact, the Egyptian authorities agreed to loan Lucas to the excavation.[7] He commenced work in December 1922,[8] a part of a small team of experienced archaeologists and experts, led by Howard Carter and including Arthur Mace, Arthur Callender and photographer Harry Burton.[9] Lucas played a key role in this team, being responsible for the conservation, restoration and preparation for shipping of the thousands of objects found, some of them quite fragile.[1] To enable him to undertake this work, a makeshift laboratory was set up in the nearby empty tomb of Seti II,[10] with Lucas, assisted by Arthur Mace, assessing, cleaning and – if necessary – repairing each object to ensure safe transport to the Cairo Museum.[11]
