Fischer has attempted to explain how a rongorongo tablet 'ideally' should be read:

I will use his pictures and text to improve on what he has written:

On side a ('Side One') the reading should begin at bottom left and move towards the right. At the end of line a1 the text continues with line a2. The beginning of line a2 is immediately above the end of a1.

The glyphs in line a2 are, though, upside down. Either you have to turn the tablet to see them in normal fashion or you must learn to read upside down glyphs. The experts on Easter Islands did not turn their tablets, they could read upside down texts.

The end of line a2 is immediately above the beginning of line a1 and immediately below the beginning of line a3. The glyphs in line a3 are oriented as those in line a1. If you have turned the tablet in order to read line a2 you must once again turn the tablet to see the glyphs with their normal orientation.

Every odd-numbered line can be easily read, while the lines with even numbers have inverted text. The text grows upwards like a vine.

Fischer then states - incorrectly - that on side b ('Side Two') the described pattern is different, that odd-numbered lines are inverted. But such is not always the case (which Fischer also later on admits).

The text lines on side b of G, for example, behave exactly as on side a. Odd-numbered lines are not inverted.
