We know from Glenn Milne's inundation data that Gozo and Malta were indeed one big island during the Ice Age, down to approximately 13,500 years ago, and that they did not take on their present form as an archipelago of three islands (with little Comino in between) until around 11,000 years ago. Accordingly, if the medieval tradition of Malta and Gozo as one big island is not a complete invention -- and why should it be? -- then, 'fantastic' though it may seem, it somehow preserves a memory of Malta as it appeared more than 11,000 years ago. It is well known that most medieval mapmakers were only copyists reproducing older maps and [...] I believe we cannot exclude the possibility that the single large island called Gaulometin of Galonia leta that has somehow survived on certain medieval maps may indeed be a representation of Malta in a much earlier time. A mental leap is required in order even to consider such a possibility. It is necessary to set aside all preconceptions about the past, and all unexamined notions of how societies evolve. Above all, we have to rid ourselves of the ingrained conviction that (despite some setbacks) the basic story of human civilization has been steadily and reassuringly onwards and upwards from the very beginning. It may not have been so. There may be tremendous gaps, of which we are blissfully unaware, in the evidence presently available to us concerning the origins and progress of civilization. In particular, there has been no sustained or serious search for very ancient underwater ruins along the millions of square kilometres of continental shelves flooded at the end of the Ice Age. So it is , and within the bounds of reason, that a civilization of some sort might have flourished during the closing millennia of the Ice Age and might not yet have been detected by archaeologists. A civilization not necessarily at all like our own but still advanced enough to have mastered complex skills such as seafaring and navigation (that do not call for a large material or industrial base) and to have left behind memories of the world as it looked before the flood and at various stages during the rising of the seas. The sort of civilization, perhaps, that would have built with megaliths and aligned them with navigational precision to the path of the sun. Maybe even a civilization that measured the earth, mapped it and netted it with a latitude and longitude grid. Until such a lost civilization has been entirely ruled out -- and we are far from that -- it is rational to keep our minds open to the possibility, however extraordinary it may seem, that certain ancient maps have indeed carried down to us broken images of the antediluvian world.
