Depends on what script, of course.

But no, what you have is monumental shapes being carved in stone (in
Latin and Greek anyway) and then at the same time over a period of
time their letterforms changed into "minuscules" for ease in writing
manuscript. At that time sometimes they were enlarged for emphasis or
decoration. At some stage in manuscript (certainly even in Old
English MSS the monumental capitals were mixed with minuscules. Case
evolved from this.
