Although Gautama Buddha was not represented in artistic form until around the 1st century CE, the physical characteristics of the Buddha are described in one of the central texts of the traditional Pali canon, the Digha Nikaya, in the "Discourse of the Marks" (Pali: Lakkhaṇa Sutta) (D.32), and are also enumerated in the Brahmāyu Sutta of the Majjhima Nikāya (MN 91).Budha was great in speaking.
These characteristics comprise 32 signs - "The 32 signs of a Great Man" (Pali: Lakkhaṇa Mahāpurisa 32) - and were supplemented by another 80 secondary characteristics (Pali:Anubyanjana) (see Brahmāyu Sutta, MN 91, for these). These traits are said to have defined the appearance of the historical Gautama Buddha and have been used symbolically in many of his representations.
In the traditions of esoteric Buddhism the 32 greater and 80 lesser marks are held to be energetic qualities of the subtle body of the Sambhogakaya.
The first statues and busts of the Buddha were made in the Gandhar (now Kandahar) region of modern day Afghanistan. The sculptors were either descendants of Greeks who settled in the region after Alexander's arrival or were influenced by Hellenistic traditions. Before any such statues were made, the Buddha was symbolised by the Dharma Wheel or simply a Stupa. The Dharma Wheel also appears on the Sarnath pillar of Ashoka.
The first representations of the Buddha were made nearly 300 years after his death. Although the holy texts and canons do contain some information about his looks, their exact authorship and time of writing is debatable.
Many statues and busts exist where the Buddha and other Boddhisatvas have a moustache. This is in keeping with the view that a man of significant stature must have a big moustache. Later versions however do not show any moustache and the Buddha is always shown clean shaven without beard. In the Pali Canon a paragraph appears many times recording the Buddha describing how he began his quest for enlightenment, saying: 
"So, at a later time, while still young, a black-haired young man endowed with the blessings of youth in the first stage of life — and while my parents, unwilling, were crying with tears streaming down their faces — I shaved off my hair & beard, put on the ochre robe and went forth from the home life into homelessness.— Ariyapariyesana Sutta
The 32 Signs of the Great Man
There are 32 main characteristics (Pali: Lakkhana Mahapurisa 32):

- The furrow between his shoulders is filled in (Pali: pitantara mso).
- The distance from hand-to-hand and head-to-toe is equal (Pali: nigrodhaparima n dalo). Note: incidentally, these are also the ideal proportions according to Vitruvius, and depicted in Leonardo Da Vinci’s Vitruvian Man.

Nila is the word used to describe a sapphire and the color of the sea, but also the color of a rain cloud. It also defines the color of the Hindu God Krishna. Note 2: "His lashes are like a cow's; his eyes are dark./ Those who know such things declare/ 'A child which such fine eyes/ will be one who's looked upon with joy./ If a layman, thus he'll be/ Pleasing to the sight of all./ If ascetic he becomes,/ Then loved as healer of folk's woes.'" (Lakkhana Sutta)
