Jysk Arkæologisk Selskabs Skrifter The Maussolleion at Halikarnassos. Reports of the Danish Archaeological Expedition to Bodrum: 6. Subterranean and Pre-Ma, Book 15, (Hardcover)

Volume 6 details Jan Zahle's investigations of subterranean structures close to the Maussolleion. Successive spoliations - including Newton's - have greatly muddled the archaeological record, and the Danish excavations uncovered evidence of another complication: plans for the site appear to have changed during construction, so what was originally intended as a modest extension of the existing structures evolved into a huge tomb on an immense terrace. His thorough sifting of evidence resolves many contradictions, though uncertainties remain.
