armor. Scholars have debated about the identity of the tomb occupants since the discovery of their remains in 1977–1978, yet recent research and forensic examination have concluded with certainty that at least one of the persons buried was Philip II (Tomb 2). Located near Tomb 1 are the above-ground ruins of a heroon, a shrine for cult worship of the dead. In 2014, the ancient Macedonian Kasta Tomb, the largest ancient tomb found in Greece (as of 2017), was discovered outside of Amphipolis, a city that was incorporated into the Macedonian realm after its capture by Philip II in 357 BC. The identity of the tomb's occupant is unknown, but archaeologists have speculated that it may be Alexander's close friend Hephaestion. The deification of Macedonian monarchs perhaps began with the death of Philip II, yet it was his son Alexander the Great who unambiguously claimed to be a living god. As pharaoh of the Egyptians, he was already entitled as Son of Ra and considered the living incarnation of Horus by his Egyptian subjects (a belief that the Ptolemaic successors of Alexander would foster for their own dynasty in Egypt). However, following his visit to the oracle of Didyma in 334 BC that suggested his divinity, he traveled to the Oracle of Zeus Ammon (the Greek equivalent of the Egyptian Amun-Ra) at the Siwa Oasis of the Libyan Desert in 332 BC to confirm his divine status. After the priest there convinced him that Philip II was merely his mortal father and Zeus his actual father, Alexander began styling himself as the 'Son of Zeus', which brought him into contention with some of his Greek subjects who adamantly believed that living men could not be immortals. Although the Seleucid and Ptolemaic diadochi successor states cultivated their own ancestral cults and deification of the rulers as part of state ideology, a similar cult did not exist in the Kingdom of Macedonia. Visual arts By the reign of Archelaus I of Macedon, the Macedonian elite started importing significantly greater customs, artwork, and art traditions from other regions of Greece. However, they still retained more archaic, perhaps Homeric funerary rites connected with the symposium and drinking rites that were typified with items such as decorative metal kraters that held the ashes of deceased Macedonian nobility in their tombs. Among these is the large bronze Derveni Krater from a 4th-century BC tomb of Thessaloniki,
