The "z" shape is a very common Latin scribal abbreviation usually used at the ends of words. It stands for "-em" most of the time, but it can represent homonyms of "-em" as well (what it expands into  depends partly on the language and partly on context).
Without the macron, this would usually be interpreted as lucum in Latin, but the macron indicates more letters have been omitted:

Lucrum or luctum? That is the question. 
[Profit or sorrow?]
