I in Mar
The inclined northern end of Salvagio is divided by a narrow sea belt from I in Mar, which has approximately a crescent form and a bulk not very different from that commonly ascribed at that time to Madeira. “I,” of course, stands for Insula or one of its derivatives, such as Illa, a word or initial applied or omitted at will. “Island in the Sea” is probably the true rendering, though formerly the initial and the two words were sometimes blended, as Tanmar or Danmar, to the confusion of geographers. A larger member of the Bahama group lying near the Florida coast would seem to fill the requirements, being naturally recognized as more at sea than Florida or Cuba. Great Abaco and Great Bahama are nearly contiguous and, considered together, would give nearly the required size and form; but it is not necessary to be individual in identification. Possibly Insula in Mar as drawn was meant to be symbolical and representative of the sea islands generally rather than to set forth any particular one of them.
