The Hippogriff of Tamerlane Chess is explained on the same Griffon page of Jeremy Good. Hippogriff moves like earlier Gryphon/Griffon/(different spellings), but is excluded from the nearby squares, that is those within the 7x7 square perimeter. Since also blockable, Hippogriff is subset of Gryphon.
1283 was year of publication of Grande Acedrez with first use of Gryphon. Timur Lenk, inventor of namesake Timur's or Tamerlane Chess (1336-1405) has Giraffe as Hippogriff, the classic Gryphon that is excluded from those near squares. So there was a hundred years to ponder better implementation of Gryphon into Hippogriff. We can presume intellectual transfer of ideas from Spain to Persia, just as there was trade continually between Inuit Arctic and Siberia.
