Yes, it's the same family. Italic is usually written with an edged nib which creates thick and thin strokes. However, the script can be just as easily written with a rounded nib such as a ballpoint, Rollerball or any round-tipped nib. This is monoline writing i.e. a single, even line throughout with no heavy and light strokes.The strong construction of the letter is the factor which gives Italic the distinctive look which has survived for centuries and there's a certain clear, elegance about Italic when it's written monoline IMO. I don't prefer it, but it is a viable alternative.

I've just realised that I've posted this "monoline" version of Italic in the "Edged nib" category.....sorry!
