Au is a vowel of Indic abugidas. In modern Indic scripts, Au is derived from the middle "Kushana" Brahmi letter , and the Gupta letter . As an Indic vowel, Au comes in two normally distinct forms: 1) as an independent letter, and 2) as a vowel sign for modifying a base consonant. Bare consonants without a modifying vowel sign have the inherent "A" vowel.

Āryabhaṭa numeration

Aryabhata used Devanagari letters for numbers, very similar to the Greek numerals, even after the invention of Indian numerals. The ौ sign was used to modify a consonant's value ×10¹⁶, but the vowel letter औ did not have an inherent value by itself.[1]

Historic Au

There are three different general early historic scripts - Brahmi and its variants, Kharoṣṭhī, and Tocharian, the so-called slanting Brahmi. Au was not found in the earliest forms of Brahmi, but was found in the more flowing forms the Kushana and Gupta . Like all Brahmic scripts, Tocharian Au has an accompanying vowel mark for modifying a base consonant. In Kharoṣṭhī, the only independent vowel letter is for the inherent A. All other independent vowels, including Au are indicated with vowel marks added to the letter A.

Brahmi Au

The Brahmi letter Au, is based on the letter O which was probably derived from the Aramaic Waw . That would make it related to the modern Latin F, V, U, W, Y and Greek Upsilon.[2] Several identifiable styles of writing the Brahmi Au can be found, most associated with a specific set of inscriptions from an artifact or diverse records from an historic period.[3] As the earliest and most geometric style of Brahmi, the letters found on the Edicts of Ashoka and other records from around that time are normally the reference form for Brahmi letters, but only being found in later styles, the reference form of Brahmi Au is back-formed from later styles to match the geometric writing style.

Brahmi Au historic forms
Ashoka (3rd-1st c. BCE)	Girnar (~150 BCE)	Kushana (~150-250 CE)	Gujarat (~250 CE)	Gupta (~350 CE)

Tocharian Au

The Tocharian letter is derived from the Brahmi . Unlike some of the consonants, Tocharian vowels do not have a Fremdzeichen form.

Kharoṣṭhī Au

The Kharoṣṭhī letter Au is indicated with the O vowel mark plus the vowel length mark . As an independent vowel, Au is indicated by adding the vowel marks to the independent vowel letter A .
