The annexed wood-cut represents a remarkably beautiful statera whichis preserved in the Museum of the Capitol at support is the trunk of a tree, round which aserpent is entwined.

Vitruvius (x. 3. s. 8. § 4) explains the principleof the steelyard, and mentions the following con-stituent parts of it: the scale (lancula) dependingfrom the head (caput), near which is the point ofrevolution (centrum) and the handle (ansa). Onthe other side of the centre from the scale is thebeam (scapus) with the weight or equipoise (aequi-pondium), which is made to move along the points(perpuncta) expressing the weights of the differentobjects that are put into the scale.
