the title Das Minoische Kreta in 1825 for volume two of his Kreta; this appears to be the first known use of the word "Minoan" to mean "ancient Cretan". Evans probably read Hoeck's book and continued using the term in his writings and findings: "To this early civilization of Crete as a whole I have proposed—and the suggestion has been generally adopted by the archaeologists of this and other countries—to apply the name 'Minoan'." Evans said that he applied it, not invented it. Hoeck, with no idea that the archaeological Crete had existed, had in mind the Crete of mythology. Although Evans' 1931 claim that the term was "unminted" before he used it was called a "brazen suggestion" by Karadimas and Momigliano, he coined its archaeological meaning. Chronology and history Instead of dating the Minoan period, archaeologists use two systems of relative chronology. The first, created by Evans and modified by later archaeologists, is based on pottery styles and imported Egyptian artifacts (which can be correlated with the Egyptian chronology). Evans' system divides the Minoan period into three major eras: early (EM), middle (MM) and late (LM). These eras are subdivided—for example, Early Minoan I, II and III (EMI, EMII, EMIII). Another dating system, proposed by Greek archaeologist Nikolaos Platon, is based on the development of architectural complexes known as "palaces" at Knossos, Phaistos, Malia and Zakros. Platon divides the Minoan period into pre-, proto-, neo- and post-palatial sub-periods. The relationship between the systems in the table includes approximate calendar dates from Warren and Hankey (1989). The Minoan eruption of Thera occurred during a mature phase of the LM IA period. Efforts to establish the volcanic eruption's date have been controversial. Radiocarbon dating has indicated a date in the late 17th centuryBC; this conflicts with estimates by archaeologists, who synchronize the eruption with conventional Egyptian chronology for a date of 1525–1500BC. Tree-ring dating using the patterns of carbon-14 captured in the tree rings from Gordion and bristlecone pines in North America indicate an eruption date around 1560BC. Overview Although stone-tool evidence suggests that hominins may have reached Crete as early as 130,000 years ago, evidence for the first anatomically-modern human presence dates to 10,000–12,000 YBP. The oldest evidence of modern human habitation on Crete is pre-ceramic Neolithic farming-community remains which date to about 7000BC. A comparative study of DNA haplogroups of modern Cretan men showed that a male founder group,
