A rare image of the reclining Child Jesus as the Good Shepherd, minutely carved in ivory. Reclining on his left side (normally the figures are resting on their right side), and with a palm frond serving as a pillow, the child lies on a bed of leaves. Presented as a dozing shepherd, and with his hair in thick curls, Jesus wears an open front short sleeved tunic made from animal skin, with the opening tied with corded straps framing the neckline. The figure stands out for the quality of its carving, the smooth modelling of the anatomy and the comeliness of the face which, with closed eyelids, reveals a meditative smile. Belongs to a distinct group of objects which has puzzled scholarship in recent years. Some of the reclining figures have the left hand resting on a small lamb kneeling over the Book of Faith, an Agnus Dei, while in other known examples the lamb appears as a strange animal. The peculiar distinguishing features of this production led Pedro Dias to propose the Kingdom of Siam as the centre of production, based on the similarity of posture between our devotional figurine and the Thai reclining Buddha in Ayutthaya, an argument which has failed to totally convince other scholars. Nevertheless, some of the iconographic peculiarities are sufficient to dispel any doubts about the Thai origin of this production. In at least two known examples, the lamb is depicted as another animal: the wild pig, or Thai boar (Sus scrofa jubatus), an endemic species peculiar to this area of Southeast Asia. The meaning of such inclusion besides proving the Thai origin of this production, indicates a type of devotion perfectly integrated into the culture and art of Siam from the Ayutthaya period, and the likely local consumption of these devotional images. Furthermore, the type and forms of the garments point to a Thai origin, given that the clothes of this Good Shepherd are reminiscent of the monastic clothing typical of this Buddhist school: the ungsa, a short sleeved tunic, and the antaravassaka, worn around the waist. Given the destruction of the city of Ayutthaya in 1767 and the disappearance of one of the largest Catholic communities in Asia these devotional statuettes stand as the best testimony to the importance of the Portuguese presence in the Kingdom of Siam during the early modern period.
