Where does “figurehead” come from?

I can't write this etymology summary because the chain provided doesn't support the word "figurehead." The chain shows: English head ← Middle English heed ← Old English hēafod ← Latin figura ← PIE kauput- ← PIE dʰeyǵʰ- This is contradictory (Latin "figura" doesn't derive from PIE "kauput-," which is the root for "head," and these don't connect logically to "figurehead"). Additionally, "figurehead" is a compound word (figure + head), but the chain only traces one element and includes Latin "figura," which would be relevant to the "figure" part, yet the sequence doesn't coherently support either component of the actual word. To write an accurate one-sentence summary, I would need a chain that actually traces "figurehead" or its components through their correct etymological paths.
