Sentinel is a font now? In my day it was a foundry name.

A natural companion for a Clarendon (such as Sentinel) would be a realist sans (Helvetica). But I don't think it's a crime to use it with Miller. See how they work together.

Where do you intend to use Sentinel: in text or for titles? You could use Trade Gothic Bold for titles. Or one of H&FJ's sans.

I think Miller is a fine choice: They both have similar skeletons, and even the italics have a lot in common. The lighter weights of Sentinel, though, may look a bit close to Miller if you're pairing them at the same size. I'd recommend using a nice different in weight or size to properly differentiate them.

As more evidence, H&FJ's own recommendations are always effective, and for Sentinel they suggest pairing it with Chronicle, a Scotch like Miller.

Ionics/Clarendons and Scotches are fine companions. The earliest examples of both arose around the same time and region.

Using a Clarendon as a bold companion for a Scotch in running text can have overtones of period typography. As in this example of Belizio (a Clarendon) with Miller Text (a Scotch):

 
I agree with Reed: keep the contrast in weight or size sufficient to differentiate their use.

Kent, your example is anachronistic -- Miller is too transitional (especially the italic "v") to be paired with a Clarendon and evoke an historic moment in time. The Scotch Modern is the "correct" historical partner for Clarendons.

However, because its slabs are not bracketed, Sentinel does evoke the earliest slab serif types, just as Miller evokes an early Scotch Roman, so the two go together historically.

> Kent, your example is anachronistic

Fair enough. Agreed. When I said “overtones of period typography,” I did not mean to imply that the pairing would have authentic verisimilitude or be genuinely allusive. Just that it would be evocative, as you say.
