Fibonacci numbers and the anagram

Fibonacci numbers and the anagram:
Sauniére has written the following on the floor:

13 3 2 21 1 1 8 5

O, Draconian devil!

Oh, lame saint

P.S. Find Robert Langdon

The first line is the Fibonacci numbers, in which each number is the same as the sum of the two previous numbers.

Phi is related to the Fibonacci numbers (1, 1, 2, 3, 5, 8, 13, 21 etc.), because the quotient of two upon each other following numbers gradually gets closer to the number phi. For every higher number the quotient will be more and more precise, and if two following numbers have the value of 987 or higher, the difference from phi will be less than 0,00001.

The order of the numbers written by Saunière have been mixed. The two next lines in the verse are anagrams, where the letters have to be exchanged to make sense. Robert and Sophie get this idea, because the Fibonacci numbers are mixed. By exchanging the letters the following code shows up:

Leonardo Da Vince

The Mona Lisa

P.S. in the last line are the initials of Princess Sophie, which Sophie always was called by Saunière. It could also mean Priory of Sion and be a message to Robert Langdon.

After having solved the riddle about the anagram, Sophie is angry with herself for not having seen this. Her grandfather, Saunière, often used anagram games to improve her ability of spelling English words. He once had written the English word PLANETS and told Sophie, that 92 other English words of different lenghts could be made out of the letters. Sophie had spent three days with an English vocabulary, until she had found them all.
