The first modern traveller of note to explore the cavern was the French botanist, G. P. de Tournefort, who spent three years, from 1700 to 1702, travelling about Asia Minor and the Levant.
Tournefort's book, as well as being a mine of information on various subjects, makes delightful reading, whether in the original French or in John Ozell's English translation of 1718, from which we quote.
"This famous place," he says, referring to the Labyrinth, which he visited on July 1, 1700, "is a subterranean Passage in manner of a Street, which by a thousand Intricacies and Windings, as it were by mere Chance, and without the least Regularity, pervades the whole Cavity or Inside of a little Hill at the foot of Mount Ida, southwards, three miles from Gortyna. The Entrance into this Labyrinth is by a natural Opening, seven or eight Paces broad, but so low that even a middle-siz'd Man can't pass through without stooping.
"The Flooring of this Entrance is very rugged and unequal; the Ceiling flat and even, terminated by divers Beds of Stone, laid horizontally one upon another.
"The first thing you come at is a kind of Cavern exceeding rustick, and gently sloping: in this there is nothing extraordinary, but as you move forward the place is perfectly surprizing; nothing but Turnings and crooked By-ways. The principal Alley, which is less perplexing than the rest, in length about 1200 Paces, leads to the further end of the Labyrinth, and concludes in two large beautiful Apartments, where Strangers rest themselves with pleasure. Tho' this Alley divides itself, at its Extremity, into two or three Branches, yet the dangerous part of the Labyrinth is not there, but rather at its Entrance, about some thirty paces from the Cavern on the left hand. If a Man strikes into any other Path, after he has gone a good way, he is so bewildered among a thousand Twistings, Twinings, Sinuosities, Crinkle-Crankles and Turn-again Lanes, that he could scarce ever get out again without the utmost danger of being lost."
He refers to various inscriptions in charcoal, mostly names of former visitors, and notes various dates ranging from 1444 to 1699. "We too," he says, "wrote the Year of the Lord 1700 in three different places, with a black stone." "After a thorow Examination of the Structure of this Labyrinth we all concurred in Opinion, that it could never have been what _Belonius_ and some other of the Moderns have fancy'd; namely, an antient Quarry, out of which were dug the Stones that built the Towns of Gortyna and Gnossus. Is it likely that they would go for Stone above a thousand paces deep, into a place so full of odd Turnings?... Again, how could they draw these Stones through a place so pinch'd in, that we were forc'd to crawl our way out for above a hundred paces together? Besides, the Mountain is so craggy and full of Precipices that we had all the difficulty in the World to ride up it.... It is likewise observable, that the Stone of this Labyrinth has neither a good Hue nor a competent Hardness; it is downright dingy, and resembling that of the Mountains near which Gortyna stands.
