Taprobana is Borneo

Ptolemy's mysterious island Taprobana is Borneo and it's quite obvious. But since the current consensus written in stone is that Taprobana was Sri Lanka, I'll spell it out with pictures.

(There is an in-depth essay on this by Dhani Irwanto (Taprobana is not Sri Lanka nor Sumatera, but Kalimantan) that I found after drawing these maps, making this quite redundant. But well.)
