For those itching to see the Ekottara Agama source of the legend of King Udayana (優填王) and King Prasenajit's (波斯匿王) statues of the Buddha in sandalwood and gold respectively, here it is from Sutta Central - http://www.cbeta.org/cgi-bin/goto.pl?li ... 5_p0703b13
. Scroll down to p0706a01 onwards.
Oddly enough, James McHugh in "Sandalwood and Carrion - Smell in Indian Religion & Culture", p.211 mentions a medieval Jain legend of an image of Mahavira made from "ox-head sandalwood". In the above Ekottara Agama sutra, we have the same sandalwood being mentioned as the material for King Udayana's statue of the Buddha -
Hmm, I wonder if the Thais would approve if they discovered that this Mahasanghika sutra is the source of one of their their Monday Buddha legends.
