Caves and the cave temples of Karnataka. History The Ajanta Caves are generally agreed to have been made in two distinct phases, the first during the 2nd century BCE to 1st century CE, and a second several centuries later. The caves consist of 36 identifiable foundations, some of them discovered after the original numbering of the caves from 1 through 29. The later-identified caves have been suffixed with the letters of the alphabet, such as 15A, identified between originally numbered caves 15 and 16. The cave numbering is a convention of convenience, and does not reflect the chronological order of their construction. Caves of the first (Satavahana) period The earliest group consists of caves 9, 10, 12, 13 and 15A. The murals in these caves depict stories from the Jatakas. Later caves reflect the artistic influence of the Gupta period, but there are differing opinions on which century in which the early caves were built. According to Walter Spink, they were made during the period 100 BCE to 100 CE, probably under the patronage of the Hindu Satavahana dynasty (230 BCE – c. 220 CE) who ruled the region. Other datings prefer the period of the Maurya Empire (300 BCE to 100 BCE). Of these, caves 9 and 10 are stupa containing worship halls of chaitya-griha form, and caves 12, 13, and 15A are vihāras (see the architecture section below for descriptions of these types). The first Satavahana period caves lacked figurative sculpture, emphasizing the stupa instead. According to Spink, once the Satavahana period caves were made, the site was not further developed for a considerable period until the mid-5th century. However, the early caves were in use during this dormant period, and Buddhist pilgrims visited the site, according to the records left by Chinese pilgrim Faxian around 400 CE. Caves of the later or Vākāṭaka period The second phase of construction at the Ajanta Caves site began in the 5th century. For a long time it was thought that the later caves were made over an extended period from the 4th to the 7th centuries CE, but in recent decades a series of studies by the leading expert on the caves, Walter M. Spink, have argued that most of the work took place over the very brief period from 460 to 480 CE, during the reign of Hindu Emperor Harishena of the Vākāṭaka dynasty. This view has been criticised
