No no! Euler redefined them as ratios in the 18th century (I think because the branch of Analysis needed it) but before that they were lengths. See Aryabhata, Bramagupta, Varāhamihira, Bhāskara ... and many more.

Trying to get into the head of Varāhamihira (6th century, India). I think he saw sine 30° as the root of a one-quarter area and sine 60° as the root of a three-quarter area. The geometric partition into ¼ and ¾ will definitely stay with me.

How old is #zero and the 0?
The Bakhshali manuscript from the Bodleian libraries provides us with some answers to that. More reason to know more about #mathematicians from South Asia - say Aryabhata, Brahmagupta, Bhaskara II, Varāhamihira, and Madhava.

Also … they weren’t working on unit circles … Varāhamihira used r=120 I think (though r=3438 was more common) … so I wonder if that makes a difference; less attractive perhaps to think of sine 30° as 60 or sine 30° as 1719.

3) The Vedic Period
Vedic Astrology, or Jyotiṣh (ज्योतिष), dates back around 4000 years.
The Brihat Samhita by Varahamihira, from the 6th century CE, includes the chapter “Dravya-Nishcaya,” where planetary combinations influence the abundance, scarcity and price of goods.

Then you have the works of an Indian astronomer named Varāhamihira (namely the Pañcasiddhāntikā), which preserve a lot of the Sasanians' astronomical expertise. Definitely check those out as well.

5️⃣ First, a bit on physiognomy—reading personal traits through physical features. The earliest texts we have, like Brihat Samhita by Varahamihira, detail Purusha-lakshanam (for men) and Stri-lakshanam (for women). They outline ideal traits for nobility, with deviations seen as less auspicious.

Continuity of the #Dholavira Scheme of Ratios and Units
CE 600, Varahamihira wrote in his Brihat Samhita (53.4 & 5) The L of a king's palace is > breadth by 4th The L of house of a commander >the width by a 6th.
Two ratios, 1+1/4 & 1+1/6, are identical to 5:4 and 7:6

Quote of the day by Varahamihira: “He Who Knows Astrology Knows the Order of Time” | – The Times of India
In the first part of the sixth century, Varahamihira, an Indian mathematician, was born. Varahamihira lived in Ujjain and was one of Chandragupta II's nine gems (Navaratnas). He wrote the Panchasiddhantaka, a collection of five astronomical treatises. Varahamihira made the calculation of Aryabhata's sine tables more accurate. His father, Adityadisha, who worshipped the Sun god, taught him astrology. Varahamihira, also called Varaha or Mihira, was an Indian philosopher, astronomer, and mathematician, who compiled Greek, Egyptian, Roman, and Indian astronomy in the Pancha-siddhantika (Five Treatises). Varahamihira was the only prominent Indian mathematician, astronomer, and astrologer whose name became well-known in India.
