Menefee argued that the ritual mirrored that of a livestock sale—the symbolic meaning of the halter; wives were even occasionally valued by weight, just like livestock. Although the halter was considered central to the "legitimacy" of the sale, Thompson has suggested that Menefee may have misunderstood the social context of the transaction. Markets were favoured not because livestock was traded there, but because they offered a public venue where the separation of husband and wife could be witnessed. Sales often took place at fairs, in front of public houses, or local landmarks such as the obelisk at Preston (1817), or Bolton's "gas pillar" (1835), where crowds could be expected to gather.
