TODAY'S THEME DAY AT CDPB: NUMBERS

These are my favourite numbers in Lisbon and around the Planet, depicting the seventieth anniversary of the most beautiful four-masted Tall Ship in the World, [CREOULA], built in Lisbon in 1937!!!... Other beautiful numbers I found in Lisbon are painted on ships' hulls and dock ladders!! They look great, don't they??...

I also found an interesting article [here] regarding Numbers, as follows: «The numbers we all use (1, 2, 3, 4, etc.) are known as "Arabic" numbers to distinguish them from the "Roman Numerals" (I, II, III, IV, V, VI, etc). Actually the Arabs popularized these numbers in the early 9th century C.E. (mainly through the work in Baghdad of al Khawarzimi who was born in Uzbekistan) but they were originally used by the early Phonecian traders to count and keep track of their trading accounts. But have you ever thought why «1» means one and «2» means two? The roman numerals are easy to understand, but what was the logic behind the phonecian numbers? It's all about angles! If one writes the numbers down (see below) on a piece of paper in their older forms, one quickly sees why.

Therefore, number 1 has one angle. number 2 has two angles. Number 3 has three angles. Number 4 (which used to be written +) has four angles. Etc. And "O" has no angles! Interesting, isn't it? An ancient phonecian manuscript explains this and I thought it to be fascinating.»
