[5] Based on the estimates of the relative ages of various personages portrayed in Lion Capital Inscriptions, Dr Stein Konow has determined that Yuvaraja Kharaosta Kamuio (i.e. son of Arta) was the father of Aiyasi Kamuia, the chief queen (Agra-Mahisi) of Saka Mahakshatrapa Rajuvula.
[8] Saka governor Rajuvula had married princess Aiyasi Kamuia, daughter of Yuvaraja Kharaosta Kamuio, probably to strengthen his political position and also his claim to the throne (of Taxila).
Many scholars including Sten Konow, H. W. Bailey, R. K. Mukerjee, K. P. Jaiswal, J. L. Kamboj, Buddha Prakash and others recognise that the names Kamuia and Kamuio (q.v) of the Mathura Lion Capital Inscriptions are the Kharoshthi/Prakritic forms of Sanskrit/Pali Kambojika or Kamboja.
[12] A recently discovered "Inscribed Silver Buddhist Reliquary", found from Shinkot in Bajaur (Pakistan), and edited and published for the first time by Richard Saloman, in Journal of the American Oriental Society (July- September 1996), refers to a king named Kharayosta, believed to belong to the later quarter of first century BCE.
According to its editor Dr Richard Salomon (University of Washington), king Kharayosta of the "Inscribed Silver Buddhist Reliquary", in all probability, is the same Kharaosta who finds reference as Yuvaraja Kharosta in the Mathura Lion Capital inscriptions as well as, as Kharaostasa or Kharahostes in the coins.
