*Mari=nos), of Tyre, a Greek geographer, who lived in the middle of the second century of the Christian era.


He was the immediate predecessor of Ptolemy, who frequently refers to him. Marinus was undoubtedly the founder of mathematical geography in antiquity; and we learn from Ptolemy's own statement (1.6) that he based his whole work upon that of Marinus. The chief merit of Marinus was, that he put an end to the uncertainty that had hitherto prevailed respecting the positions of places, by assigning to each its latitude and longitude. He also constructed maps for his works on much improved principles, which are spoken of under PTOLEMAEUS. In order to obtain as much accuracy as possible, Marinus was indefatigable in studying the works of his predecessors, the diaries kept by travellers, and every available source. He made many alterations in the second edition of his work, and would have still further improved it if he had not been carried off by an untimely death.
