Grave Circle A, Mycenae in the context of "Treasure of Villena"

Rubble masonry or rubble stone is rough, uneven building stone not laid in regular courses. It may form an outer surface of a wall, or fill the core of a wall which is faced with unit masonry such as brick or ashlar. Some medieval cathedral walls have outer shells of ashlar with an inner backfill of mortarless rubble and dirt.

A shaft tomb or shaft grave is a type of deep rectangular burial structure, similar in shape to the much shallower cist grave, containing a floor of pebbles, walls of rubble masonry, and a roof constructed of wooden planks.

The death masks of Mycenae are a series of golden funerary masks found on buried bodies within a burial site titled Grave Circle A, located within the ancient Greek city of Mycenae. There are seven discovered masks in total, found with the burials of six adult males and one male child. There were no women who had masks. They were discovered by Heinrich Schliemann during his 1876 excavation of Mycenae.

There is also a death mask found in Grave Circle B, but it differs from the Circle A masks both in material, as it is made from electrum, and placement, as it was placed in a container besides an entombed body, rather than being placed upon the deceased. The relative scarcity of death masks in Grave Circle B indicate that the buried dead were of lesser wealth or status, rather than Grave Circle A with an abundance of material made from valuable materials, such as the Death masks.

Georg Heinrich Karo (11 January 1872 – 12 November 1963) was a German archaeologist who specialised in Mycenaean and Etruscan civilisation. He was twice director of the German Archaeological Institute at Athens (DAI), in which capacity he excavated the Mycenaean site of Tiryns. A colleague of Wilhelm Dörpfeld, who had worked with Heinrich Schliemann at Troy, Karo published the findings from Schliemann's excavations of Grave Circle A at Mycenae. The work was considered Karo's greatest contribution to scholarship.

Karo was born into a prosperous merchant family; both of his parents were non-practising Jews, who raised him as a Protestant Christian. Initially inclined towards classical philology, he became interested in archaeology as a student of Georg Loeschcke at the University of Bonn. After earning his doctorate from Bonn in 1896, Karo travelled widely in the Mediterranean region, developing interests in Minoan civilisation, the Etruscans and ancient biblical commentaries. He taught at Bonn between 1902 and 1905, before moving to the DAI in Athens as Dörpfeld's deputy. Known for his urbane manner and fluency in several languages, he became well connected in the international circles of Greek archaeology, and maintained the favour of both the Greek and the German royal families. His outspoken German nationalism led to his dismissal from the DAI in 1916: he spent some time in the Ottoman Empire, where he worked to conserve cultural heritage and was linked with various efforts to appropriate ancient artefacts and bring them to Germany.

Grave Circle B in Mycenae is a 17th–16th century BCE royal cemetery situated outside the late Bronze Age citadel of Mycenae, southern Greece. This burial complex was constructed outside the fortification walls of Mycenae and together with Grave Circle A represent one of the major characteristics of the early phase of the Mycenaean civilization.
