The only arhat described as an elderly man with a goatee is Bhadra, who normally does the gesture of turning the wheel of dharma with both hands. The above holds a long-life vase and another object.
Several arhats may hold a manuscript, but the prayer wheel in the left hand doesn’t correspond to standard iconography.
This old and curious sculpture depicts an arhat holding a small elephant in his left hand. The tiny lion attached to the base points to Chudapantaka, who normally has both hands in the meditation gesture.
This remarkable work also departs from any standard arhat iconography. The right hand seems to have held a manuscript, a bowl or an incense burner.
