[ScG, the ford of Fódla].
In ancient times Atholl was one of the four Pictish kingdoms, roughly equivalent with what was until 1974 Perthshire, now north-west Tayside. On the modern map Atholl is a mountainous, forested area at the south end of the Grampian mountains. The land is generally uncultivatable, but it has an extensive deer forest. Many Scotsmen perceive Atholl as a kind of impenetrable interior or ‘heartland’ of the Highlands.
